Characterization of Web server workload

Realistic and formal mathematical description of web-server workload forms a fundamental step in the design of synthetic workload generators, capacity planning and accurate predictions of performance measures. In this thesis we perform detailed empirical analysis of the web workload by analyzing access logs of nine web-servers. Unlike most previous work that focused on request-based workload characterization, we analyze both request and session characteristics. We perform rigorous statistical analysis to determine the self-similarity of web traffic and heavy-tailedness of the distribution of different session parameters. Our analysis shows that web traffic is self-similar and the degree of self-similarity is proportional to the workload intensity. To increase the confidence in our analysis we use several methods for estimating the degree of self-similarity and heavy-tailedness. Additionally we point out specific problems associated with these methods. Finally, we analyze the impact of robots sessions on the heavy-tailedness of the distribution

Analysis of Vertically Oriented Coupled Shear Wall Interconnected with Coupling Beams

The nonlinear static response of a vertically oriented coupled wall subjected to horizontal loading is presented in this research article. The 3 storey vertically oriented coupled wall interconnected with coupling beams is modelled as solid elements in a finite element (FE) software named Abaqus CAE and the steel reinforcement is modelled as a wire element. For simulation of concrete models, a concrete damaged plasticity constitutive model is taken into consideration in this research. Moreover, with the help of concrete damage plasticity parameters, validation of two rectangular planar walls was executed with an error of less than 10 percent. Finally, these parameters are used for modeling and analyzing the static behavior of coupled walls connected with coupling beams. Furthermore, the maximum unidirectional horizontal loading helped in obtaining the compression and tensile damage as well as scalar stiffness degradation. Significantly, the research also found the plastic hinge location in the coupled wall as well as in the coupling beam, which are of utmost importance in nonlinear analysis. Doi: 10.28991/HIJ-2022-03-02-010 Full Text: PD

Subclass of bi-univalent function associated to Chebyshev polynomial

The Chebyshev polynomials are utilized in this study to define the subclass of the bi-univalent function. Also, Chebyshev polynomial bounds and Fekete-Szego inequalities for functions defined in the classes are established.Comment: 7 Page

Extramedullary plasmacytoma of the uterine cervix arising in an asymptomatic 46-year-old female

An extramedullary plasmacytoma is a rare type of plasma cell tumour that can be found in soft tissues throughout the body. The most common location for an extramedullary plasmacytoma is in the head and neck region. Few case reports have previously documented patients with an extramedullary plasmacytoma within the female genital tract. We report a case of a healthy and asymptomatic 46-year-old female who presented to Colposcopy Clinic with a finding of low-grade squamous intraepithelial lesion seen on a routine Pap smear. She was found to have a cervical polyp that was excised. Pathology revealed diffuse sheets of atypical plasma cells with lambda light chain restriction. She was referred to Hematology for extensive work-up as the pathology finding was concerning for a plasma cell neoplasm. Staging investigations, including bone marrow biopsy, skeletal survey, whole body PET-CT scan, serum protein electrophoresis, and serum free light chain testing, were all negative. Surgical resection with a hysterectomy was recommended as the most appropriate course of management. The treatment approach is consistent with guidelines outlined in the literature, whereby extramedullary plasmacytomas, which arise outside of the head and neck region and have clear margins, should undergo surgical resection. Extramedullary plasmacytomas carry a risk of progressing to systemic disease, such as multiple myeloma, making it crucial that these patients be followed with routine surveillance to achieve the most optimal long term survival outcome

Growth Response And Production Efficiency Of Broiler Chicks Treated By Different Zeolite Spreading Frequency On Litter Base

The objective of this research was to study the growth and efficiency of broiler productivity. The research was conducted through the application of zeolite spreading treatment into the broiler housing in Non-ruminant Research Station of Animal Science Laboratory of Papua State University. Study was arranged by Randomized Sample Design with four treatments: P0 (control; without zeolite spreading); P1 (once time spreading during the research period); P3 (three times application of spreading during the research period); and P5 (five times of spreading or once a week during the research period). The application of zeolite spreading was not significantly influenced the rate growth of broiler, though there is a tendency increasing weight gain along with the increased in zeolite spreading level on the litter base. P3 (three times of zeolite spreading during research) produce the feed efficiency of 0.53. Economically, Income Over Feed Chick and Zeolite Cost (IOFCZC) per head per housing unit with the application of zeolite spreading more demand compared to housing units without spreading treatment

Optimal Parameter of Tuned Liquid Column Damper attached to SDOF System Subjected to periodic loading

Optimal parameter of tuned liquid column damper (TLCD )namely Frequency Ratio, Length ratio and Mass ratio are evaluated for single Degree of Freedom (SDOF) system fitted with TLCD. Equation of motion for the SDOF-TLCD system has written, it is dynamically coupled equation. Coupled equation of motion is uncoupled by applying orthogonally condition and each uncoupled equations are solved and response are combined to get maximum displacement. Response of system for different values of frequency ratio, Mass ratio and length ratio are evaluated and graphs are plotted. From the graph optimal parameters are evaluated and finally conclusions are drawn

Antiphospholipid (Hughes) syndrome: beyond pregnancy morbidity and thrombosis

The antiphospholipid syndrome is an autoimmune disease characterised by recurrent arterial or venous thrombosis, pregnancy morbidity and the persistence of positive antiphospholipid antibodies. Many other clinical manifestations may occur including heart valve disease, livedo reticularis, thrombocytopenia and neurological manifestations such as migraine and seizures. We review a number of other manfestations including stenotic lesions, coronary artery disease and accelerated atherosclerosis, skeletal disorders and the concept of seronegative antiphospholipid syndrome

Chronic Toxicity Study For Tamra Bhasma (A Generic Ayurvedic Mineral Formulation) in Laboratory Animals

Tamra Bhasma – a generic Ayurvedic mineral formulation was studied for its toxicity in laboratory animals. Chronic toxicity was conducted in albino rats (wistar strain). In this study Tamra Bhasma was administered orally, daily to different groups of albino rats in TD (Tamra Bhasma) and 2 TD (Tamra Bhasma 2 x Therapeutic Doses) doses for 3 months. Tamra Bhasma was found to be relatively safe at these dose levels. There was no mortality. No significant behavioural changes were noted in any of the group studied. No major alterations were observed in haematology, serum biochemical, necropsy and histopathology at the administered dose level. The overall chronic toxicity study data indicates that the test substance at its TD and 2TD level is very well tolerated since no toxicity symptoms of serious cause could be observed in any of the parameters analysed
