Collection and protection of digital evidences in audit processesDenetim süreçlerinde dijital delillerin elde edilmesi ve korunması

Wide usage of information technologies in banking, finance, health and other commercial sectors requires performing of audit of these sectors through information systems. Collecting and protecting electronic evidence is critically important for both judicial process and results of audit activities. Gathering electronic evidences from an information system is a subject for computer forensics and requires special expertise and equipment. Conversely, in Turkey, most of the  institutions responsible for  supervision of financial and other relevant sectors have not enough knowledge and experience about forensic audit. Due to the absence of technical knowledge and tools, there would be deficiencies in collecting electronic evidence in accurate manner. In order to prevent these deficiencies, some alternative solutions are offered in this study. These solutions are adapting the computer forensic techniques to audit processes, providing appropriate training to auditors, establishing a legal environment, sharing of information system audit resource and outsourcing of forensic audit activities. ÖzetBankacılık, finans, sağlık ve diğer ticari sektörlerde bilgi teknolojilerinin kullanımının artması, denetim faaliyetlerinin de bilgi sistemleri üzerinden gerçekleştirilmesi gereksinimini doğurmaktadır. Elektronik ortamlardan dijital delil elde edilmesi ve korunması hem denetim faaliyetinin sonuçları hem de adli süreç açısından önem taşımaktadır. Dijital delillerin elde edilmesi ve korunması adli bilişim faaliyeti kapsamına girmektedir. Adli bilişim faaliyeti uzmanlık ve özel donanımların kullanımını gerektirmektedir.

Cutoff values of NT-proBNP for the prediction of low functional capacity, decreased ejection fraction and cardiovascular events in patients with heart failure

Background: It has been demonstrated in numerous studies that N-terminal pro-B-type natriuretic peptide (NT-proBNP) is strongly associated with left ventricular ejection fraction (LVEF), functional capacity (FC), and cardiovascular (CV) mortality in heart failure (HF) patients. The aim of the present study was to determine the predictive cutoff values of NT-proBNP for predicting these parameters. Methods: One hundred HF patients (88 male, 12 female, mean age 53.6 &#177; 8.9 years) with left ventricular (LV) systolic dysfunction and impaired exercise capacity were enrolled into the study. Echocardiographic examination was performed. The NT-proBNP concentration was measured after resting for 20 min in the supine position. The modified Bruce protocol was utilized for exercise testing. The patients were followed for between 690 and 840 days (mean 750 &#177; 30 days) for the occurrence of CV events. Results: There was a strong negative correlation between NT-proBNP concentration and LVEF (p < 0.004). It was found that NT-proBNP is a strong predictor of LVEF < 30% (p < 0.001). When 940 pg/mL was accepted as a cutoff value for NT-proBNP for the prediction of an LVEF < 30%, the sensitivity and the specificity were 89.8% and 71.4%, respectively. NT-proBNP and left atrial diastolic dimension were the most significant parameters for predicting FC (p < 0.001, each one). An NT-proBNP cutoff value of 940 pg/mL responded to 78.8% sensitivity and 81% specificity for the prediction of FC < 5 METs. The observed independent predictors for the CV events were NT-proBNP, LV mass index, and resting heart rate (p < 0.001, p = 0.02 and p = 0.006, respectively). Every 1000 pg/mL elevation in NT-proBNP level resulted in a 27% increase in the occurrence of CV events (p < 0.006). Moreover, 940 pg/mL NT-proBNP cutoff value revealed a sensitivity and specificity of 86.7% and 64.7% respectively for the prediction of incident CV events. Conclusions: Use of NT-proBNP cutoff values is easy and reliable method for the prediction of low FC and decreased LVEF, and may aid identification of patients at the highest risk for future CV events. We suggest to use NT-proBNP cutoff value of 940 pg/mL for predicting these parameters

Preparation of Immobilised 17&beta;-Estradiol-Imprinted Nanoparticles onto Bacterial Cellulose Nanofibres to Use for the Removal of 17&beta;-Estradiol from Wastewater

Estradiol, a phenolic steroid oestrogen, is one of the endocrine-disrupting chemicals (EDCs) found in natural and tap waters. The detection and removal of EDCs is attracting attention daily as they negatively affect animals&rsquo; and humans&rsquo; endocrine functions and physiological conditions. Therefore, developing a fast and practical method for the selective removal of EDCs from waters is essential. In this study, we prepared 17&beta;-estradiol (E2)-imprinted HEMA-based nanoparticles onto bacterial cellulose nanofibres (E2-NP/BC-NFs) to use for the removal of E2 from wastewater. FT-IR and NMR confirmed the structure of the functional monomer. The composite system was characterised by BET, SEM, &micro;CT, contact angle, and swelling tests. Additionally, the non-imprinted bacterial cellulose nanofibres (NIP/BC-NFs) were prepared to compare the results of E2-NP/BC-NFs. Adsorption of E2 from aqueous solutions was performed in batch mode and investigated via several parameters for optimisation conditions. The effect of pH studies was examined in the 4.0&ndash;8.0 range using acetate and phosphate buffers and a concentration of E2 of 0.5 mg/mL. The maximum E2 adsorption amount was 254 &micro;g/g phosphate buffer at 45 &deg;C. The experimental data show that the Langmuir is a relevant isotherm model for E2 adsorption. Additionally, the relevant kinetic model was the pseudo-second-order kinetic model. It was observed that the adsorption process reached equilibrium in less than 20 min. The E2 adsorption decreased with the increase in salt at varying salt concentrations. The selectivity studies were performed using cholesterol and stigmasterol as competing steroids. The results show that E2 is 46.0 times more selective than cholesterol and 21.0 times more selective than stigmasterol. According to the results, the relative selectivity coefficients for E2/cholesterol and E2/stigmasterol were 8.38 and 86.6 times greater for E2-NP/BC-NFs than for E2-NP/BC-NFs, respectively. The synthesised composite systems were repeated ten times to assess the reusability of E2-NP/BC-NFs

Atık Sulardan Estradiol Uzaklaştırılması İçin E2 Baskılanmış Nanopartikül Bakteriyel Selüloz Kompozit Sistemin Hazırlanması

Many environmental disruptors from various sources act as Endocrine Disrupting Chemicals and have adverse effects on natural life and on human by effecting endocrine system functions. Individual effects may lead to social problems. In natural life, effects of endocrine disruptors appear as reproductive system and developmental anomalies. It was reported that plasma vitellogenin level in fish living near wastewater treatment plants in the United Kingdom increases due to steroids, oestrogen and alkylphenols in streams and thus feminization in male fish occurs. Natural hormone 17β-oestradiol and contraceptive 17α-ethinylestradiol are the most potent oestrogens and small concentrations in wastewater treatment plants has advers effects on fish reproduction. E2 is a natural hormone effecting the improvement and progression of sexual characteristics, and also the maturation and function of sexual organs. Also found in male in small amounts. E2 is also associated with neuroendocrine system and bone structure and may promote cancer in target organs. Like all steroids, E2 has the same cyclopentan-o- perhydrophenanthrene ring as main component cholesterol. Main ring structure consists of three hexagonal and a pentagonal rings. Like other steroids, 8 E2 is also characterized with phenolic ring. It has also a hydroxyl group in β position of C17 carbon. In this thesis, removal of trace amounts of 17β-oestradiol from wastewaters by molecular imprinting technique is aimed.Çeşitli kaynaklardan gelen birçok çevresel kirletici endokrin bozucu kimyasallar (EDC) olarak davranabilir ve endokrin sistemin normal fonksiyonlarını etkileyerek, maruz kalan tabi yaşam ve insanlar üzerinde olumsuz etkilere neden olur. Bireysel etkiler daha sonra tüm toplumu etkileyecek şekilde ilerleyebilir. Doğal yaşamda, endokrin bozucuların etkileri en çok üreme sistemi ve gelişme anormallikleriyle ortaya çıkmaktadır. İngiltere’de atıksu işleme fabrikalarının yakınında yaşayan balıklarda plazma vitellogenin (estrojen bağımlı plazma proteini) seviyelerinin, akıntılarda steroidler, estrojen ve alkilfenollerin varlığıyla arttığı ve bunun sonucu olarak erkek balıklarda feminizasyon gözlendiği rapor edilmiştir. Doğal hormon 17β-estradiol ve yapay doğum kontrol hapı 17α-etinilestradiol en potansiyel estrojenlerdir ve bazı atıksu işleme tesislerinde düşük derişimlerde bulunmaları balıkların üremesi üzerinde değişikliklere yol açabilmektedir. E2; dişi cinsiyet karakteristiklerinin gelişimi, devamını ve cinsiyet organlarının olgunlaşmasını ve fonksiyonunu etkileyen doğal hormondur. Az miktarda olmakla birlikte bu hormon erkeklerde de bulunmaktadır. E2 aynı zamanda 6 nöroendokrin sistem ve kemik yapısıyla da bağlantılıdır ve hedef dokularda kanser oluşumunu kolaylaştırabilmektedir. Tüm steroidler gibi E2 de ana bileşik kolesterol ile aynı siklopentan-o-perhidrofenantren halkasına sahiptir. Temel halka yapısı üç hekzagonal halka ve bir pentagonal halkadan oluşmaktadır. Diğer steroidler gibi, E2 de fenolik halka ile karakterize edilmektedir. Ayrıca, molekül düzleminin üzerinde C17’nin β pozisyonunda bir hidroksil grubuna sahiptir. Bu kapsamda, bu tezde moleküler baskılama yöntemi kullanılarak eser miktardaki 17β-estradiol’ün uzaklaştırılması hedeflenmiştir

Accurate And Robust Pneumatic Position Control

Tez (Yüksek Lisans) -- İstanbul Teknik Üniversitesi, Fen Bilimleri Enstitüsü, 1998Thesis (M.Sc.) -- İstanbul Technical University, Institute of Science and Technology, 1998Pnömatik konum kontrolü havanın sıkıştırılabilirliği ve sürecin temelde termodinamik bir süreç olması nedeniyle karmaşık bir problemdir. Ancak sistemin yüksek mertebeden olması ve darbe yutucu özellikleri, bilgisayarla kontrol durumunda düşük maliyetli donanımla akıllı kontrol algoritmalarının kullanılmasına uygundur. Bu çalışmada bu tür uygulamaların deneysel sınanmasını sağlayacak donanım tanıtılmaktadır. Hız geri beslemeli ikili kontrol, kayan rejimli ikili kontrol, darbe genişliği modülasyonu ve sürekli basınç kontrolü bu donanımla gerçekleştirilmiş, elde edilen sonuçlar karşılaştırmalı biçimde irdelenmiştir. Bu çalışmada, doğrusal hareket yapan bir pnömatik silindirin, çalışma alanı içinde farklı referans konumları için katı ve hassas konumlamasını yapacak bilgisayar kontrollü, düşük maliyetli, basit donanım yapısına sahip, ancak akıllı hareket algoritmalarının da uygulanabileceği çok amaçlı bir deney tesisatı kurulmuştur. Bu amaçla kurulan deney tesisatında 1adet çubuksuz silindir, 1 adet sayısal ölçüm yapabilen bir cetvel, 2 adet basınç ölçer, kumanda valfi olarak ikili kontrol uygulamaları için 2 adet hızlı(20 Hz.), 3/2 aç-kapa valf, sürekli kontrol için ise 2 adet 3 yollu basınç oransal valfleri kullanılmıştır. Sistem bilgisayara Advantech PCL-PG-812 endüstriyel arayüz kartı ile bağlanmış ve gerekli tüm yazılım Borland C++ dilinde yazılmıştır. Tesisat üzerinde konum kontrolünün istenilen şekilde yapılabilmesi için çeşitli kontrol algoritmaları dener ek, karşılaştırmaları yapılmıştır. Araştırmada "konum kontrolunda ±0,1 mm.'den iyi kesinlik" ve "dış kuvvet değişimlerinde en fazla ±5 mm. sapma" hedef alınmıştır. Yapılan deneyler sonucunda, hız geri beslemeli ikili kontrolün en hızlı cevap veren yöntem olmasına rağmen aşma meydana geldiği ve sistem mertebesinin yüksek olması sonucu birkaç salınımdan sonra referansa oturduğu, kayan rejimli kontrolde aşma yapmadan referansa oturduğu, ancak oturma zamanının hız geri beslemeli kontrole göre fazla olduğu, sistem parametrelerinin değişimine duyarsız olduğu görülmüştür. Her iki kontrol teknolojisi de referans etrafında aynı katılığa sahiptir. Darbe genişliği modülasyonunda ise valfleri sürekli aç-kapa yapmasından dolayı referans etrafında aynı derecede katı davranmadığı ve bozan etkenlere duyarlı olduğu, oransal basınç kontrolünün ise en hassas ve yumuşak davranışa yol açtığı, sistem katılığının çeşitli yöntemlerle istenilen mertebeye ayarlanabileceği görülmüştür.The purpose of this study is the realisation of accurate and robust pneumatic position control by experimental testing of new methods like Velocity Feedback On-Off Control, Sliding Mode Control, Pulse Width Modulation Control, Continuous Pressure Control. To realise an accurate and robust position control, new algorithms for pneumatic cylinders are investigated and applied to experimental test bench. The objective of this research is the determination of dimensioning, system design and control principles to realise "accuracy better than ±0,1 mm. for position control " and "max deviation of 5 mm. under external force variations". Pneumatic Position Control is widely used in food industry and packaging systems because it is a "clean" technology and preferred in mechanical positioning operations where large fo..e/torqi.^s are not necessary, because its components are comparatively cheap with respect to hydraulic and electromechanical components. However, pneumatic position control is more complicated than hydraulic and electrical position control. Air compressibility emerges as an important issue when accurate and robust position control is desired against of external force variations. Technological developments in measurement and control components (accuracy of measurement systems, fast switching directional valves) with advances in Intelligent Motion Control methods and increase of the computational speed prepared the necessary scientific and technological basis to develop performance and low cost solutions to this problem. To observe the effects of the developing algorithms on a real time system, an experimental test bench is constructed (Figure S.l). A sufficiently accurate linear scale (600mm,20um/pulse resolution) are coupled to a double acting rodless XI pneumatic cylinder (500mm) with high precision guide to measure the piston displacement. The cylinder is suitable to be used in robotic applications. To drive the pneumatic cylinder, for application of on-off control theory, two 3/2 on-off valves and for application of continuous time control theory, two 3 way pressure proportional valves are added to pneumatic position control system. Two pressure sensors are used to observe the changes in the pressure at the two chambers in the cylinder. The system has been controlled in "real time" by a computer (486 DX-25) using necesssary interface cards. The control program is written in the C language and the control law is implemented with a sampling period of 7,5 ms. The velocity signals are obtained by differentiating and digitally filtering the position measurements. Pb Pb Figure S. 1 General structure of pneumatic position control system Effects of technological parameters (friction, valve delays, digital measurement resolution, sampling period, external force magnitudes, dynamical behavior parameters of the system) on system performance are investigated and solution methods are developed. Results obtained from this work can be applied and generalized to Pneumatic Velocity and Force Control Systems. In the recent years, pneumatic position systems is especially used in robotic applications. This applications have caused the development of pneumatic position control systems. At the beginning although proportional valves are very expensive, Xll manufacturers have used pneumatic proportional valves. Instead of using very expensive proportional valves to reach a high accuracy, on-off valves, cheaper than proportional valves, can be used in pneumatic position control. On the other hand, to achieve precision position control by using on-off valves, it is necessary to investigate in detail the dynamical behaviour of the system. To achieve accurate pneumatic position control, a mathematical model is derived for a symmetrical linear actuator which drives a mass with viscous and coulomb friction. By selecting, xi=y X2= V X3=Pl X4=P2 system equations may be written in state-space form as; xi =x0 ~B A / N FS X2 = x_ + - -(x, -x.) *- x3 yıo + xı -x2.x3 + R.T q A VT.a x4 = y20 ' Xl x2.x4 + RT \_ A Vf a.Y" Control technologies applied to system can be considered in three parts. These are; 1- On-off control a- Velocity feedback on-off control b- Sliding mode control 2- Pulse width modulation control 3- Continuous pressure control xiii The first control algorithm applied to the pneumatic system is on-off control. In this control, valve is completely on or off. Control signal is; u=sign(yref-y) This control technology causes oscillations around reference position. If dead-zone is large, load stops around the reference point. This is not accurate and robust position control. Another control algorithm is basically same with the on-off control but in addition to on-off control, velocity feedback control is added to on-off control algorithm. Control signal is; u=sign[(yref-y)-Kv.y] This type of control is applicable for position control. The behaviour of the system strongly depends on Kv. If Kv is increased, control signal changes very frequently and that will cause increasing of the settling time. Adding dead zone around the reference point is essential for stopping oscillations. The width of the dead zone must be smaller than the d<. red position accuracy. Velocity feedback control shows the minimum time control characteristics. At the high values of Kv, control signal changes frequently and motion of load is not affected from parameter variations. Frequent signal changing will cause pressure oscillations in chambers of the cylinder. The system behaves as an overdamped systems. Settling time will increase, system will be much accurate and robust according to the low values of the Kv and there will not be an overshoot. This type of control is called Sliding Mode Control. Otherwise, smaller Kv values decreases the settling time, but the system behave as underdamped system and can oscillate around the reference point. Pulse width modulation is often useful to control the voltage across a motor in such a way that only two values are used, usually zero and some other value. The usefulness derives from two sources: XIV a- The easiest signal to produce with a computer is a binary signal b- Most efficient way to modulate power flow is with amplifiers that can only operate at full-on or full-off. Control signal is derived from a control parameter, a. According to this parameter, it is decided which part of a period, control signal will be on or off. a= 0,5+ 0,4.u* Figure S. 2 Characteristic of u*- a A pulse width modulated signal is a constant frequency, two-valued signal in which the proportion of the period for which the signal is on and the proportion for which it is off can be varied. For pulse width modulation to be effective, the chosen frequency of the PWM signal must be high enough so that valve will not have time to respond to the rapid on-off changes, but, instead, the speed of the valve will reflect the average power level over many cycles. This average power level is controlled by the duty cycle. Shortly, to reach an accurate and robust position control, control parameters must be adjusted carefully. XV Continuous pressure control technique is applied to the system to compare the control efficiency of on-off and continuous pressure control. The valve used in our system, can control the pressure between 0,5 and 6,5 bar (gauge). For deriving 0-6,5 bar, 0-1 ampere must be sent to valve. Au is a control signal. uı= ü+Au, U2= ü-Au Au=Kp.(yref-y) - Kv.y Experimental investigation on the robustness of the system has shown that, if dead zones are the same, velocity feedback on-off control has a same robustness with sliding mode control at the reference point. But, settling time of sliding mode control is bigger than settling time of velocity feedback on-off control. However, there is not an overshoot at the sliding mode control. Although robustnesses of these control are the same, maximum errors at reference point are different, velocity feedback on-off control 0,5 mm., sliding mode control 0,3 mm. The behavior of PWM control at reference point is not robust enough because of continuously changing position of valves. Maximum error at reference point is around 0,6 mm. Application of continuous pressure control at the position control is completely new approach. Continuous pressure control has a good robustness, maximum error around 0,2 mm (Figure S.3). Algorithm of velocity feedback, SMC and PWM are easy but algorithm of Continuous Pressure Control is complex. In other terms, adjustment of control parameters in SMC and Continuous Pressure Control are difficult and parameter variations affect the quality of control. In conclusion, desired accuracy ± 0,1 mm is not achieved at this stage but it is shown that this problem can be solved by using a cylinder which has a low friction coefficient and difficulty of control parameter adjustment is also shown. If cost price, accuracy and robustness of control technologies are compared, most optimal qualifications will be found at sliding mode control. XVI 0,5 1 1,5 2 time(sec.)

Silisyum Güneş Hücrelerinin Veriminin Üstçevrim ile Artırılması için Çift Dalgaboyunda Yansıma Yapabilen Dağılımlı Bragg Yansıtıcı Tasarımı ve Üretimi

Tek eklemli güneş hücrelerinde iki temel enerji kaybı vardır. Bunlardan birincisi bant aralığından düşük enerjili fotonların soğurulamaması; ikincisi, bant aralığından daha yüksek enerjiye sahip fotonların ürettiği elektron-deşik çiftlerinin enerjisinin bant aralığı seviyesindeki bir enerji değerine ısı yayarak düşmeleridir. Güneş hücrelerinin temel kayıplarının azaltılması, tayfın yeniden şekillendirilmesi ile gerçekleştirilebilir. Bu işlem, yüksek enerjili fotonların iki veya daha fazla daha düşük enerjili fotona dönüştürülmesi (alt-çevrim) veya enerjisi soğurucu malzeme bant aralığından küçük olduğu için soğrulamayacak olan iki veya daha fazla fotonun, enerjisi bant aralığından daha fazla olan bir fotona dönüştürülmesi (üst-çevrim) ile gerçekleşir. Bu çalışmada silisyum güneş hücrelerinde kullanılmak üzere, dağılımlı Bragg yansıtıcı yapısı erbiyum iyonlarının temel emisyon ve birinci üst-çevrim bantlarındaki ışığın silisyum güneş hücresine geri yansıması için tasarlanmış ve üretilmiştir. Toplam 5 adet amorf silisyum ve silisyum dioksit çiftine sahip olan bu yapı ile 980 nm dalgaboyu civarında %90 ve 1550 nm dalgaboyu civarında ise %95’in üzerinde yansıma elde edilmiştir. Bu çalışmada geliştirilen dağılımlı Bragg yansıtıcı yapısı silisyum güneş hücrelerinin verimini artırmak için maliyet etkin bir yaklaşımdır

Filiz, Ertugrul/0000-0001-9636-6389; Ozyigit, Ibrahim Ilker/0000-0002-0825-5951WOS: 000339103800013PubMed: 24781980Superoxide dismutase (SOD, EC 1.15.1.1) is an enzyme catalyzing the dismutation of superoxide radical to hydrogen peroxide and dioxygen. To date, four types of SODs - Cu/ZnSOD, MnSOD, FeSOD, and NiSOD - have been identified. In this study, SOD proteins of Brachypodium distachyon (L.) Beauv. were screened by utilization of bioinformatics approaches. According to our results, Mn/FeSODs and Cu/ZnSODs of B. distachyon were found to be in basic and acidic character, respectively. Domain analyzes of SOD proteins revealed that iron/manganese SOD and copper/zinc SOD were within studied SOD proteins. Based on the seconder structure analyzes, Mn/FeSODs and Cu/ZnSODs of B. distachyon were found as having similar sheets, turns and coils. Although helical structures were noticed in the types of Mn/FeSODs, no the type of Cu/ZnSODs were identified having helical structures. The predicted binding sites of Fe/MnSODs and Cu/ZnSODs were confirmed for having His-His-Asp-His and His-His-His-Asp-Ser residues with different positions, respectively. The 3D structure analyzes of SODs revealed that some structural divergences were observed in patterns of SODs domains. Based on phylogenetic analysis, Mn/FeSODs were found to have similarities whereas Cu/ZnSODs were clustered independently in phylogenetic tree
