Reachability Based Web Page Ranking Using Wavelets
AbstractA naĂŻve approach has been made by applying the concept of reachability for web page ranking and implementing multi resolution analysis using Haar wavelet to order the web pages. In this article, page ranking has been done by developing a structured signal using in links, out links and reachability values of the web pages of network graphs. Using Haar wavelet, the page ranking is proposed and developed. The average and detailed coefficients of the input signal and the down sampling process provides the necessary page ranking of web pages. This approach does not involve any iterative technique, damping factor or initialization of the page ranks. In this paper, comparison between the original page rank, category-based page rank and the proposed approach have been made. The result reflects the role of paths between the pages in page rankings
An Ayurvedic approach to Low Back Pain
Low back pain is the leading cause of activity limitation and work absence throughout much of the world, imposing a high economic burden on individuals, families, communities, industry and governments. It is a prevalent condition that afflicts about 70% of people in developing countries at some point in their lifetime. Ayurvedic classical terms such as Katishoola, Kati Graha, Trika Shoola and Gridhrasi are used for describing the low back pain. The pain localized to low back can be considered under Katishoola and pain along with stiffness are included under Katigraha and Pain radiating to lower limb are considered under Gridhrasi. Treatment modalities which are beneficial for pacifying Vata such as Vatasaya Upakrama and Vatavyadhi Chikitsa are used in treating conditions of low back pain. Specific Chikitsa Sutras mentioned for the Katishoola, Katigraha, Trikashoola and Gridhrasi are to be followed in low back pain. To prevent the reoccurrence, lifestyle modification and low back strengthening exercise are to be advised
A Comparative Study of Text Summarization Based on Synchronous and Asynchronous PSO
Text summarization is the process of extracting the most important sentences from the original document without its meaning change. The paper focus on Extractive summarization technique which chooses the important sentences from the document and integrates into summary. An extractive summarization technique, Particle swarm Optimization performs arithmetic operations that enhances a problem, by iteratively trying to improve possible solution with regard to input data. It determines a problem by having a population of possible solutions moving around the search space according to arithmetic formulae over the particles position and velocity. The sequence of modernized particles of PSO can be categorized into Synchronous PSO (S-PSO) and Asynchronous PSO(A-PSO). In synchronous PSO, after calculating the whole performance, velocities and positions of the particles are modernized, this increases the performance. In A-PSO after calculating its performance, velocities and positions of the particles are modernized using partial data which leads to extreme analysis. The comparative study on the synchronous PSO and asynchronous PSO with the precision and recall values for different datasets is considered. Asynchronous PSO has higher precision and recall values compared to synchronous PSO. Asynchronous PSO leads to extreme analysis of data
Design and Development of Mono Leaf Spring by using Composite Material (Epoxy-Carbon Fiber)
According to the demand of recent world, the more concentration is on weight reduction in automobiles. The possible weight reductions are wheel assembly, axles, and part of the weight of suspension spring and shock absorbers. The leaf spring accounts for 10-20% of the un-sprung weight. The composite materials made it possible to reduce the weight of machine element without any reduction of the load carrying capacity. Because of composite material\u27s high elastic strain energy storage capacity and high strength-to weight ratio compared with those of steel. FRP spring also have excellent fatigue resistance and durability. But the weight reduction of the leaf spring is achieved not only by material replacement but also by design optimization. Weight reduction has been the focus of automobile manufacturers in the present scenario. The replacement of steel with optimally designed composite leaf spring can provide 75%-78% weight reduction. The material selected is carbon epoxy against conventional steel. The optimization study consists of use of software\u27s such as NASTRAN / ANSYS software. The experimentation on UTM is carried out and results are compared. Moreover, the composite leaf spring has lower stresses compared to steel spring. All these will result in fuel saving which will make countries energy independent because fuel saved is fuel produced
Mycotic Lesions in Surgical Pathology.
The Fungal Diseases Are Grouped Arbitrarily Into Four Broad Categories Based On
The Predominant Location Of Infection Within The Body As Superficial, Cutaneous,
Subcutaneous And Systemic Infection. Superficial Mycoses Are Those In Which The Fungus
Is Usually Confined To The Keratinized Layer Of The Skin And Its Appendages. The
Cutaneous And Subcutaneous Mycoses Are A Polymorphic Group Of Diseases Caused By A
Variety Of Fungi. Systemic Mycoses Usually Have A Pulmonary Inception From Which
They Disseminate To Other Organs.
Most Fungal Infections Occur Because A Person Is Exposed To A Source Of Fungi
Such As Spores On Surfaces Or In The Air, Soil Or Bird Dropings. Usually There Is A Break Or
Deficiency In The Bodys Immune System Defences And The Person Provides The “Right
Environment” For The Fungi To Grow. Any One Can Have A Fungal Infection But Certain
Populations Are At Increased Risk Of Fungal Infections And Recurrence Of The Infection.
These Include HIV–AIDS Spectrum, Malignancy, Multidrug Resistant Tuberculosis,
Diabetes Mellitus, Organ Transplant Recipients, Those Who Are On Chemotherapy Or
Immunosuppressants, Prolonged Intake Of Steroids For Chronic Disorders Like Bronchial
Asthma, Rheumatoid Arthritis And Inborn Immunological Deficiencies. Neutropenic
Patients Are Prone To Develop Invasive Mycosis. Persons Who Have Undergone
Abdominal Or Cardiac Surgery And Those Who Received Repeated Intravenous Injections
Are At Risk Of Mycoses. In The Macroscopic Evaluation Of Tissue Specimens, Mycotic
Infections Are Frequently Mistaken For Neoplasms Or Other Diseases And A Mycosis Often
May Not Be Considered Until The Histopathological Examination Is Complete2.
There Are Four Basic Approaches To The Diagnonsis Of Mycotic Diseases: (1)
Clinical (2) Mycologic (3) Immunologic (4) Pathologic. Diseases Caused By Fungi May
Be Difficult To Distinguish Both Clinically And Pathologically From Those Caused By Other
Microbial Agents. Because Serological Test Have Certain Limitations And Have Not Been
Developed For Some Fungal Diseases, A Definitive Diagnosis Of Mycotic Disease Often
Rests On Direct Microscopic Demonstration Of A Fungus In Tissues And Exudates, Or On
Isolating And Identifying It In Culture. Histopathology Should Not Be A Substitute For
Mycologic Culture ; Rather The Two Should Complement Each Other Whenever
Possible.Histopathologic Evaluation Provides Indisputable Evidence Of Tissue Invasion
And Therefore Can Confirm The Pathogenic Significance Of A Cultural Isolate That Belongs
To The Body Flora Or That Is Usually Encountered As An Environmental Contaminant In
Culture. Histopathology Can Also Confirm The Presence Of Coexisting Infections By Other
Fungi, Bacteria, Viruses And Protozoans Thus Guiding The Clinician In The Selecting The
Most Appropriate Therapy And Management For The Patient. Although Some Fungi And
Related Organisms Can Be Detected In Hematoxylin And Eosin Stained Tissue Sections,
Special Histochemical Stains Are Usually Necessary To Demonstrate Their Morphology In
Detail. Fungi Can Be Adequately Detected In Cytologic Specimens Obtained By Fine Needle
Aspiration Biopsy, Brushing, Washing Or Scraping. A Drawback Of Cytologic Specimens
However May Be The Inability To Distinguish Invasive Fungal Infections From Fungal
Colonization1.
The Three Common Fungal Stains Used Are Gomori Methenamine Silver
(GMS)5,36, The Gridley Fungus (GF), And The Periodic Acid – Schiff (PAS) Procedures.
GMS Procedure Is Considered To Be The Best Of The Special Fungal Stains For Screening A
Tissue Section Because It Provides Better Contrast And Stains Fungal Cells That Are
Refractory To The GF And PAS Procedures
Improved Performance of DPFC Using Sliding Mode Controller Method
Modern power systems demand the need of active power flow with the help of Power Electronics control devices is needed. In the family of Flexible AC Transmission devices (FACTS), Dynamic PFC (DPFC) offers the same controlling function as Unified PFC (UPFC), comprising the control of transmission angle, bus voltage and line impedance. A technical modification of UPFC is DPFC in which fluctuations of voltage at DC link is eliminated that enables the individual operation as series and parallel controllers. The concept of DFACTS is used in design of the series converter. The replacement of the high rating three phase series converter with the multiple low rating single phase converters results in cost reduction and increases reliability greatly. This DC Link is used to transfer the real power between two converters in UPFC such as in DPFC which eliminates the 3rd harmonic frequencies at transmission lines. D-FACTS converters are acting as insulation between high voltage phases acts as 1-ᴓ floating with respect to ground. These results in lower cost for the DPFC system compared to the UPFC. This paper describes the comparison of PI and Sliding Mode Controllers which conclude that SMC is a better control strategy compared to PI
DPFC Performance with the Comparison of PI and ANN Controller
Modern power systems demand the active control of power flow and for this purpose Power flow controlling devices (PFCDs) are required. Distributed FACTS Controller (DPFC) is a part of FACTS family. DPFC offers equal control ability same as UPFC, comprising the adjustment of the internal angle of the machine and bus voltage includes line impedance. In addition to UPFC a new device evolved known as DPFC in which common DC link is eliminated that enables the exclusive working between the two converters which are shunt and the series. The Distributed-FACTS (D- FACTS) idea is adopt in the series converter scheme. The replacement of the high rating three phase series converter with the multiple low rating single phase converters results in cost reduction and increases reliability greatly. The useful power transfer between the two converters which are shunt and series through common dc link in UPFC where as in DPFC in this the required power is transferred in the transmission line with three times of natural fundamental frequency. Where as in the new device no need of large voltage separation between the line and PFC Device is no requirement of high voltage isolation between because D-FACTS converters which are 1-ᴓ floating device with respect to the ground. Accordingly, In this paper we bring out the DPFC performance differences with different control techniques which are PI and Artificial Neural Network Controllers and bring with conclusion that ANN is a better control strategy compared to PI
