Load Balancing Scheduling Algorithm for Concurrent Workflow

Concurrent workflow scheduling algorithm works in three phases, namely rank computation, tasks selection, and resource selection. In this paper, we introduce a new ranking algorithm that computes the rank of a task, based on its successor rank and its predecessors average communication time, instead of its successors rank. The advantage of this ranking algorithm is that two dependent tasks are assigned to the same machine and as a result the scheduled length is reduced. The task selection phase selects a ready task from each workflow and creates a task pool. The resource selection phase initially assigns tasks using min-min heuristic, after initial assignment, tasks are moved from the highly loaded machines to the lightly loaded machines. Our resource selection algorithm increases the load balance among the resources due to tasks assignment heuristic and reassignment of tasks from the highly loaded machines. The simulation results show that our proposed scheduling algorithm performs better over existing approaches in terms of load balance, makespan and turnaround time

Knowledge Graph Enhanced Aspect-Level Sentiment Analysis

In this paper, we propose a novel method to enhance sentiment analysis by addressing the challenge of context-specific word meanings. It combines the advantages of a BERT model with a knowledge graph based synonym data. This synergy leverages a dynamic attention mechanism to develop a knowledge-driven state vector. For classifying sentiments linked to specific aspects, the approach constructs a memory bank integrating positional data. The data are then analyzed using a DCGRU to pinpoint sentiment characteristics related to specific aspect terms. Experiments on three widely used datasets demonstrate the superior performance of our method in sentiment classification

Relationship between the Wechsler Intelligence Scale for Children - fourth edition (WISC-IV) subtests and reading ability.

This research report attempts to identify the relationship between subtests of the Wechsler Intelligence Scale for Children (WISC-IV) and reading, using the Neale Analysis of Reading – Revised (NEALE-R). The subtests of the WISC-IV used for this study are Vocabulary, Similarities, Comprehension, Word Reasoning and Digit Span. These subtests have similar properties to the skills needed for reading. The study included a sample of 33 Grade 2 boys and girls attending an English-medium, private school in Gauteng. Parametric and non parametric tests were run on the sample due to the small size of the sample. Results showed statistically significant relationships between variables like the Word Reasoning, subtest and the Similarities subtests. Analyses were also run separately on the gender groups to determine any correlations between specific gender and reading ability. Significant correlations were found between the Similarities subtest of the WISC-IV and the Accuracy subtest of the Neale-R; and Word Reasoning on the WISCIV and Comprehension on the Neale-R. However overall on gender analysis showed a decrease in difference on performance levels between boys and girls

CORDIC algorithm and it’s applications in DSP

OBJECTIVE: The digital signal processing landscape has long been dominated by the microprocessors with enhancements such as single cycle multiply-accumulate instructions and special addressing modes. While these processors are low cost and offer extreme flexibility, they are often not fast enough for truly demanding DSP tasks. The advent of reconfigurable logic computers permits the higher speeds of dedicated hardware solutions at costs that are competitive with the traditional software approach. Unfortunately algorithms optimized for these microprocessors based systems do not map well into hardware. While hardware efficient solutions often exist, the dominance of the software systems has kept these solutions out of the spotlight. Among these hardware- efficient algorithms is a class of iterative solutions for trigonometric and other transcendental functions that use only shifts and adds to perform. The trigonometric functions are based on vector rotations, while other functions such as square root are implemented using an incremental expression of the desired function. The trigonometric algorithm is called CORDIC an acronym for Coordinate Rotation Digital Computer. The incremental functions are performed with a very simple extension to the hardware architecture and while not CORDIC in the strict sense, are often included because of the close similarity. The CORDIC algorithms generally produce one additional bit of accuracy for each iteration. DESCRIPTION: A detailed study on various modes of CORDIC algorithm is done. First of all a study is made how the CORDIC algorithm is derived from the general vector equation. Then a study is done regarding the various modes of the CORDIC algorithm and how it can be used to find the sine, cosine, tan and logarithm functions, its use in conversion of coordinate systems. An attempt is made to carry out a rigorous study of its use in DSP oriented applications AND how it has revolutionized the DSP scenario. Finally simulations are carried out using MATLAB to support the purpose of our study. RESULTS The results clearly bring out the advantage of using CORDIC algorithm. First of all the sine and cosine of any angle could be found out easily. Similar is the case of logarithm and hyperbolic functions. The simulation results prove the fact that the hardware complexity gets reduced by using the CORDIC algorithm. A large no of plots were obtained for different 7 functions. Finally the implementation in DCT was carried out and the results obtained were in line with those of the theoretical values. CONCLUSION The CORDIC algorithms presented in this paper are well known in the research and super computing circles. Here the basic CORDIC algorithm and a partial list of potential applications of potential applications of a CORDIC based processor array to digital signal processing is presented. The CORDIC based DCT architecture for low power design has been proposed. The proposed multiplierless CORDIC based DCT architecture produces high throughput and is easy to implementing VLSI. The proposed architecture reduced the input data range for the CORDIC processor by split and the no of compensation iterations in CORDIC based DCT computation by utilizing that most images have similar neighboring pixels. The project also shows that a tool is available for use in FPGA based computing machines, which are the likely basis for the next generation DSP systems

Delayed Manifestation of Transurethral Syndrome as a Complication of Transurethral Prostatic Resection

Metabolic encephalopathy as a part of ‘transurethral syndrome’ is an immediate complication following transurethral resection of prostate. It occurs during or few hours after the surgery. However, delayed manifestation of this complication is rare. It is also possible that pretreatment with diuretics can exaggerate this problem by predisposing the patient to electrolyte abnormalities. Here we present a report of such a patient who manifested with neurological complications six days after the prostate surger

Drug utilization study-pattern of use of anti-microbial drugs among post operative patients in department of general surgery at a tertiary care hospital

Background: The objective of this study was to assess the current trends of prescribing antibiotics amongst the patients of General surgery postoperative unit of C. U. Shah Medical College and Hospital, Surendranagar, Gujarat.Methods: An observational study was done amongst 200 patients admitted in the General surgery postoperative ward of a C. U. Shah Medical College and Hospital, Surendranagar over a period of 6 months in accordance with the ethical principles of the ethics committee guidelines. Data were analyzed using Microsoft Office Excel 2007 and values were presented descriptively in percentiles.Results: The average number of antimicrobials per encounter was 1.78. The most common surgeries in the postsurgical unit were urological procedures 61 (30.35%) followed by incision and drainage 40 (20%). Most of the patients were in the age group of 35-60 yrs. Higher utilization of cephalosporins (62.91%) and fluoroquinolones (20.27%). The most preferred route of administration of antibiotics in post operative period was oral (55.58%).Conclusions: The present study provides valuable insight about the overall pattern of anti-microbials used in postoperative patients in a tertiary care hospital. It is intended to be a step in broader evaluation of safety and efficacy of drug as well as for improving prescribing habits among the fraternity and minimizing incidence of resistance to antimicrobials in surgical wards of a teaching hospital
