Energy aware routing and traffic management for software defined networks

2nd IEEE International Conference on Network Softwarization, NetSoft 2016; Seoul; South Korea; 6 June 2016 through 10 June 2016Since traffic diversity and volume increase with growing popularity of mobile applications, there is the strong need to manage the traffic carried by networks. Software defined networks can simplify network management while enabling new services by employing traffic management including routing whose goal is to maximize the given utility while satisfying capacity requirements. In this paper, we propose an efficient routing algorithm to minimize the cost based on power consumption determined by the number of active OpenFlow switches in a software defined network while satisfying throughput requirements of all flows according to constraints on link capacities in the network. We evaluate the performance of the proposed algorithm based on the number of active switches for different network topologies with various scenarios

Incremental construction of classifier and discriminant ensembles

We discuss approaches to incrementally construct an ensemble. The first constructs an ensemble of classifiers choosing a subset from a larger set, and the second constructs an ensemble of discriminants, where a classifier is used for some classes only. We investigate criteria including accuracy, significant improvement, diversity, correlation, and the role of search direction. For discriminant ensembles, we test subset selection and trees. Fusion is by voting or by a linear model. Using 14 classifiers on 38 data sets. incremental search finds small, accurate ensembles in polynomial time. The discriminant ensemble uses a subset of discriminants and is simpler, interpretable, and accurate. We see that an incremental ensemble has higher accuracy than bagging and random subspace method; and it has a comparable accuracy to AdaBoost. but fewer classifiers.We would like to thank the three anonymous referees and the editor for their constructive comments, pointers to related literature, and pertinent questions which allowed us to better situate our work as well as organize the ms and improve the presentation.

Evaluation of Physical Exercise'S Effects on Low Back Pain Among University Students With Short Form-36 and Oswestry Disability Index

DergiPark: 762681tmsjAims: This study aims to investigate the main effects of physical exercise on lower back pain with the Short Form-36 Health Survey and Oswestry Disability Index scores. Methods: University students between 18-25 years old who suffer from low back pain were enrolled in the study. Short Form-36 Health Survey and Oswestry Disability Index were used as the reference scales of lower back pain and quality of life, respectively. There are some questions in the questionnaire to scale the average comfort of the place they sleep and sit during the day, which is the result of the Personal Comfort Score. The Mann-Whitney U test was used for non-normal distributed variables. Correlation and Linear Regression were used to analyze data. SPSS 25.0 was used for all statistical analysis. Results: A total of 139 university students (94 females, 45 males) were included in the study. The median age was 20 years (IQR=2) for female students and 20 years (IQR=1) for male students. Oswestry Disability Index scores of fe- male students were higher, while Short Form-36 scores were lower than the male students. Male students' physical functioning scores were higher than female students. Each one-unit increase in Personal Comfort Score is associated with an increase in the rate between the energy/fatigue (3.34 units). Body Mass Index considerably affected the pain and Oswestry Disability Score, an increase in one unit of baseline BMI upsurged the Short Form-36 pain score to 0.13, and Oswestry disability score to 0.55. Conc- lusion: In our study, Body Mass Index is found to be associated with Oswestry Disability Index and Short Form-36 score, which are used for the severity of low back pain and defining the life quality and of patients. PCS had a positive correlation between energy/fatigue. In addition, There was a positive correlation between physical exercise and general health score

DESIGN AND IMPLEMENTATION OF AN AUTONOMOUS VEHICLE FOR WASTE MATERIAL COLLECTION AND FIRE DETECTION

Autonomous vehicles are becoming increasingly popular in a variety of applications, including waste collection and fire detection. In this work, we present the design and implementation of an autonomous vehicle for these tasks in urban environments. The vehicle is equipped with sensors and control algorithms to navigate, detect and collect plastic bottle wastes, and detect fires in real-time. The system uses an off-the-shelf, small-sized, battery-operated vehicle, a simple conveyor belt, and a vision-based, computerized system. Machine learning (ML-) based vision tasks are implemented to direct the vehicle to waste locations and initiate the waste removal process. A fire detection and alarm system are also incorporated, using a camera and machine learning algorithms to detect flames automatically. The vehicle was tested in a simulated urban environment, and the results demonstrate its effectiveness in waste material collection and fire detection. The proposed system has the potential to improve the efficiency and safety of such tasks in urban areas

New concepts for traffic, resource and mobility management in software-defined mobile networks

The evolution of mobile telecommunication networks is accompanied by new demands for the performance, portability, elasticity, and energy efficiency of network functions. Network Function Virtualization (NFV), Software Defined Networking (SDN), and cloud service technologies are claimed to be able to provide most of the capabilities. However, great leap forward will only be achieved if resource, traffic, and mobility management methods of mobile network services can efficiently utilize these technologies. This paper conceptualizes the future requirements of mobile networks and proposes new concepts and solutions in the form of Software-Defined Mobile Networks (SDMN) leveraging SDN, NFV and cloud technologies. We evaluate the proposed solutions through testbed implementations and simulations. The results reveal that our proposed SDMN enhancements supports heterogeneity in wireless networks with performance improvements through programmable interfaces and centralized control

.Bu tezin, veri tabanı üzerinden yayınlanma izni bulunmamaktadır.ÖZET Anahtar kelime: Siklonlar, Önısıtıcı siklonlar Isı değiştirici olarak kullanılan önısıtıcı siklonlar; çok kademeli olarak çimento prosesinde, çimento hammaddesi olan farinin baca gazlan ile ısıtılmasında kullamlmaktadır. Önısıtıcı siklonlarda ısı geçiş işlemi yapılırken diğer bir yandan da gaz ve farini bir birinden ayırma işlemi yapılmaktadır. Bu ayrışma sonunda tutulabilen farinin tane boyutları siklonun verimi ile doğrudan alakalıdır. Bu nedenle siklon giriş hızı, giriş sıcaklığı ve partikül konsantrasyonu sabit kaldığı taktirde siklonun geometrik parametrelerinden olan siklon dalma borusunun, derinlik değişimi ile tane boyutu oranlarmm nasıl bir eğilim gösterdiğinin bilinmesi gerekmektedir. Bu çalışmada, siklon dalma borusu (siklon çıkış borusu) derinlik değişiminin partikül boyut dağılımına etkisi deneysel olarak incelenmiştir. Deney sonunda elde edilen verilere göre, dalma borusunun derinliği arttırıldıkça partikül tutma verim artışına parelel olarak, tutulan partikül gurubu içerisindeki, küçük çaplı partiküllerin miktanmn artığı gözlemlenmiştir. Buda siklon çalışma mekanizmasından beklenen fiziksel etkilemeyi göstermekte ve doğrulamaktadır. vmTHE EFFECTS OF GEOMETRY ON PARTICULATE SIZE DISTRIBUTION IN PRE-HEATER CYCLONES SUMMARY Keywords: Cyclones, Pre-heater cyclones Pre-heater cyclones that are designed as multi stages and heat exchanger, are used to heating the cement raw meal, with hot gases leaving rotary kiln. Pre-heater cyclones are also apparatus utilizing for separating particles from gas. Collected particulate sizes are directly related on collecting efficiency. Therefore if cyclone inlet velocity, inlet temperature, and inlet concentration are constant, particulate size distribution has to be obtain at various vortex pipe depths. In this study, it is investigate that effect of vortex pipe depth on particulate size distribution in a pre-heater cyclone. According to after obtained experimental results, when vortex pipe depth is increased, collected particulate size has been fine as collecting efficiency. This results have confirmed and shown to expected physical effect. I

A rare case of transdermal methanol intoxication

WOS: 000405279400003Introduction: Methanol is a clear, colorless, and highly toxic liquid which is a common component of antifreeze solutions, paints, varnishes, gasoline mixtures, and various solvents. Even though methanol is used only in industry, when ingested accidentally or for suicide it may cause methanol intoxication which has high mortality rates. Methanol intoxication is generally seen after accidental or suicidal oral intake. Methanol can be absorbed by inhalation or through the skin, which rarely leads to clinical toxicity. Case Report: Herein, we present a case of methanol intoxication associated with absorption through the skin which is one of the rare ways of poisoning. We aim to emphasize that methanol intoxication rarely occurs after dermal exposure. Conclusion: Emergency department physicians must consider methanol intoxication in patients of high anion gap metabolic acidosis with visual symptoms even if the patient has no history of oral intake
