The major purpose of this study is to find out the extent to which previous knowledge of Book-keeping will predict students’ academic performance in Principles of Accounts 1 (BED 111) at the NCE 100 level in College of Education, Ikere Ekiti, Ekiti State, Nigeria. The study employed an ex-post facto research design with a sample of 371 selected from a population of 708. Three research hypotheses were tested at 0.05 level of significant using T-test, Standard deviation, Multiple regression and Analysis of variance. A finding from the study reveals that previous knowledge of Book-keeping significantly contributes to the prediction of academic performance of students in Principles of Accounts 1 (BED 111) among others. It was concluded that the influence of previous knowledge in teaching/learning process provides the background to framework upon which new learning will be placed. It is recommended that Joint Admission Matriculation Board (JAMB) should properly streamline
The Students’ Variables as Predictor of Secondary School Students’ Performance in Physics in Ekiti West Local Government Area of Ekiti State, Nigeria was investigated in this study. The study adopted a survey research design of the ex-post facto type. The sample comprised 120 senior secondary school II Physics students drawn from the six secondary schools in Ekiti West Local Government Area of Ekiti state. The instruments used for the study was questionnaire and past academic performance in Physics of the students involved in the study. Two research hypotheses were generated and analysed in the study using Pearson’s Moment Correlation and Multiple regression statistical analysis. Among others, the study revealed that: students‘ variables (study habit, attitude to and interest of students in Physics) are better predictors of students’ performance in Physics, while student gender has no influence on students academic performance (is a poor predictor).
In Communication system, the system capacity and performance are adversely affected and degraded by interference. Hence, power control plays a prominent role in an interference-limited system, which increases the efficiency by mitigating the adjacent and co-Channel interference in the system. In this paper, primarily power control is said to be used in maintaining the acceptable Carrier to Interference Ratio (CIR) by meeting some Quality of service (QoS) requirements Objective function that is defined as maximum channel capacity in a power constraint scenario. The signals in a radio channel undergo different propagation effects like reflection, refraction, scattering and shadowing. Hence, the distribution of users across subcarrier groups as well as their transmission powers within a given cell has a significant effect on how users and power are accordingly distributed elsewhere in the network to maximize the capacity of the system thereby enhancing its performance
Well-organized big data get together in the densely distributed sensor networks is, therefore, a challenging research area. One of the most effective solutions to address this challenge is to utilize the sink node’s mobility to facilitate the data gathering. While this technique can reduce energy consumption of the sensor nodes, the use of mobile sink presents additional Challenges such as determining the sink node’s trajectory and cluster formation prior to data collection. In this paper, we propose a new mobile sink routing and data gathering method through network clustering based on modified ExpectationMaximization (EM) technique. In addition, we derive an optimal number of clusters to minimize the energy consumption. The effectiveness of our proposal is verified through numerical results.
- In this paper, we will enlist the process of extracting template from heterogeneous Web Pages. Extracting structured information from semi-structured machine readable web pages automatically plays a major role these days, so some websites are using common templates with contents to populate the data for good productivity, Where WWW is the major resource for extracting the information. The problem here is for machines, the templates in the web pages are considered to be harmful since they degrade the performance of web applications due to irrelevant terms in the Template. As a result, the performance of the entire system degrades. Template Detection technique can be used to improve the performance of search engine as well as for classification of web documents. In this paper, we present algorithms to extract templates from a very large number of web pages that are getting generated from heterogeneous templates. Using the similarity of template structures in the documen
Rice–wheat cropping system is very common in India. It contributes to over 70% of total food grain production in the country with an area of 12 M ha under this cropping system. However, it is estimated that under rice and wheat crops separately the area is 42.31 and 22.98 M ha respectively. Looking to the above facts a study at farmer’s field of Ambedkar Nagar district was under taken to evaluate the performance of zero-till seed cum ferti-drill along with other system of wheat seeding. The zero-tillage technique may be adopted successfully for seeding to grow wheat after rice by using zero-till ferti seeddrill (ZTFDS) developed at GBPUA&T, Pantnagar and now manufactured commercial. Although this method of wheat seeding using zero-till seed cum ferti drill is becoming very popular in Haryana and Punjab states but it is not popular in U. P. particularly in central Uttar Pradesh. The zero-tillage sowing was found to be most time saving (88%) and energy efficient (79%)
This paper presents an enhanced 32-bit carry lookahead(CLA) adder implementing using the constant delay (CD) logic, targeting at full-custom high-speed applications. The CD characteristic of this logic style regardless of the logic type makes it suitable in implementing complicated logic expressions such as addition. CD logic exhibits a unique characteristic where the output is pre-evaluated before the inputs from the preceding stage is ready. This feature offers performance advantage over static and dynamic domino logic styles in a single-cycle multistage circuit block. Several design considerations including timing window width adjustment and clock distribution are discussed. Using 65-nm general-purpose CMOS technology, the proposed logic demonstrates an average speed up of 94% and 56% over static and dynamic domino logic, respectively, in five different logic gates. Simulation results of 8-bit ripple carry adders show that CD logic is 39% and 23% faster than
Even a small transition delays and little faults create major concern in digital circuits. It Produce greater impact on not only for simple memory but also for most of the memory applications. This paper presents an error-detection method for difference-set cyclic codes with majority logic decoding. Majority logic decodable codes are suitable for memory applications due to their capability to correct a large number of errors. However, they require a large decoding time that impacts memory performance. The proposed fault-detection method significantly reduces memory access time when there is no error in the data read. The technique uses the majority logic decoder itself to detect failures, which makes the area overhead minimal and keeps the extra power consumption low. The proposed method detects the occurrences of single error, double error ,triple error in the received code words obtained from the memory system.
Phonics skills are considered to be the predictors of reading disability, which is off late viewed as a language based disorder. The aim of the present study is to compare the phonics skills of high and low academic achievers across Bengali and English. A checklist consisting of three parameters was developed in both the languages to assess phonics skills. A total of 42 normally developing bilingual females who attended standard three to standard five in the age range eight to eleven years participated in the study. The participants were classified as high and low academic achiever based upon school performance. Significant differences were found in all the phonics skills in both the languages except vowel sound skill in Bengali and letter name in English. It is concluded that phonics tasks should be provided importance and during classroom curriculum as it distinguishes between high academic achievers from the low academic achievers.
Cooling tower is an important part of power plant. The efficiency of power plant is directly depends on the effectiveness of cooling tower. In cooling tower scheduled maintenance and shutdown maintenance is a problem which affects its effectiveness and performance of cooling tower. In cooling tower shutdown maintenance required in every 2 to 3 year periods at this period the whole plant will be shutdown, and require 28 to 35 days maintenance so that cooling tower will be in its best working condition. In every cooling tower manufacturer provide the scheduled maintenance check list so that the worker will perform their maintenance as per given instruction. In present work optimization of shutdown maintenance strategy is done so that the time elapsed in maintenance will reduce and the requirement of man power will be reduced.
