Sindhi language lacks computational linguistics resources for deep syntactic analysis. This paper presents a work on computational morphology and grammar development of Sindhi Language. An LFG (Lexical Functional Grammar) based model for Sindhi grammar is developed where morphological constructions are modeled in Xerox Lexicon Compiler (LEXC), and syntactic constructions are modeled in LFG by using Xerox Linguistic Environment (XLE). While developing morphology and syntax of Sindhi, different part of speech classes, phrase structures, tense, aspect, mood and agreement are considered wherever applicable. The developed computational grammar is tested against two different test suites. First test suite contains 617 handcrafted sentences in 10 different test files containing sentences with different syntactic features. Second test suite contains real time corpus of two text books of Sindhi class one with 258 sentences. Results show 98.05% and 96.5% parsing percentage of test suite 1 and test suite 2 respectively.
信德语缺乏深度句法分析的计算语言学资源。本文介绍了一项关于信德语计算形态学和语法发展的工作。提出了一种基于词法功能语法(LFG)的信德语语法模型，其中词法结构在Xerox Lexicon Compiler (LEXC)中建模，句法结构在Xerox Linguistic Environment (XLE)中建模。在发展信德语的形态和句法时，考虑到不同的词类、短语结构、时态、相位、语气和一致性。开发的计算语法针对两个不同的测试套件进行测试。第一个测试套件在10个不同的测试文件中包含617个手工制作的句子，这些测试文件包含具有不同语法特征的句子。第二个测试套件包含两本信德语一级教材的实时语料库，共258个句子。结果显示，测试套件1和测试套件2的解析率分别为98.05%和96.5%。

In AC power networks, the use of harmonic and reactive power compensations through active power filters has become emerging aspect of today’s commercial market. With the advancement of new technologies, loads based on power electronics are regularly being used in low and medium voltage distribution systems, which eventually cause the harmonics in the system currents and voltages. The most dangerous harmonics are the later i-e, 3rd , 5th , 7th and so on, which are basically result of current harmonics. They cause degradation in the performance and working of other important power system equipment. In order to mitigate these daunting harmonics, the best option is to use the hybrid power filters which combine the characteristics of both active and passive harmonic filters al-together. The main idea of this research is to model an industrial network and to perform an analysis over the Total Harmonic Distortion (THD) in the power system. The use of Hybrid Active Power (HAPF) kept the THD value well below 8%, as recommended by European Standard EN50160. With the implementation of HAPF, an additional advantage of power factor improvement was also achieved. PQ theorem was used for calculating parameters of hysteresis control used for filter implementation. Results presented in the research paper confirm the efficiency of designed filter because the THDs of both voltage and current were restricted to 2% and the system power factor was improved too. The major contribution of this research is that power quality was improved most economically using P-Q technique through HAPF.

The simplex algorithm is a powerful technique, widely used to find the optimal solution of linear programming problems. Pivot rule is the most important first step of the simplex algorithm in the maximization degeneracy problems of LP for selecting the entering variable/work column (to obtain the smallest ratios) and after than leaving variable for pivot equation. The selection of an effective pivot rule leads the smallest number of iterations of the optimal solution of L.P. The selecting of most negative number (for entering variable) in the maximization problems is known as G.B Dantzig's pivot rule. The purpose of this paper is to model an algorithm that improves in the entering and leaving variable for the maximization degeneracy problems of LP. In this article, we have introduced a powerful technique for pivot rule which reduces the number of iterations to obtain the optimal solution as compare to Dantzig’s pivot rule. This article gives better concept of selection the entering variable as well leaving variable. This article also gives a helpful imminent into the unique and constructive performance of the proposed method by coverage computational experiments.

FSO (free space optical) communication is one of the most advanced modes of wireless communication. FSO is a line of sight communication which is used to convey data from an optical transmitter to an optical receiver through atmosphere. FSO offers higher data rates but fading level due to atmospheric effects (like sand, dust, fog, rain, snow etc.) are higher than RF (radio frequency) technology. The atmosphere affects the laser beam passing through it. The atmospheric turbulence and scattering results in the degradation of the signal. In this research paper is focused and analyzes the variations in the visibility and attenuation with respect to the concentration of aerosol particles (suspended elemental particles) is done. This research work is conducted and dust model is designed in the atmosphere of urban area of Lahore city. The model deals the effect of the size of the dust particles on the visibility of FSO link and suggests a formula for the calculation of attenuation generated in the link.

A study was carried out to evaluate the impact of watercourse lining on water distribution (warabandi).For this study two watercourses, one lined (8-CL) and other unlined (11-R) of Laiqpur ex-Ali Bahar Minor were selected.The Theil’s Index was calculated on the basis of various parameters such as NIA (Net Irrigated Area), NWA (Net Wetted Area), CCA (Cultivable Command Area) and frequency of irrigation, actual TWA (Total Wetted Area) and predicted TWA (Total Wetted Area) and found as 0.22 and 0.496 for lined and unlined watercourses respectively. Hence, the effectiveness of warabandi was found as 78 and 50.4% for lined and unlined water courses respectively. The Theil’s Index values for head (31.07 acres), middle (31.76 acres) and tail (28.35 acres) sections of one lined and two unlined sections of the lined watercourse were determined as 0.147, 0.165 and 0.319 respectively, however for unlined watercourse, the Theil’s Index values were 0.21 (head), 0.5 (middle) and 0.6 (tail). This showed that in a lined section of the watercourse No. 8-CL, the effectiveness of warabandi was 85%, at its tail section it was 68% and that for tail section of the earthen w/c was only 40%. Variation of TIC in lined and unlined watercourse was 0.17 and 0.38 respectively. The conveyance loss per 1000 ft. in lined and unlined sections of watercourse 8-CL was 1.23% and 4.92% respectively, however in watercourse 11-R that was 4.9%. The conveyance efficiency in lined and unlined sections of the lined watercourse was98.76 and 90.60% and that for earthen watercourse was 70.59% and after lining, the cropping intensity increased up to 8%.

This paper introduces the adaptive noise cancellation technique for the noise reduction in Robust Automatic Speech Recognition. The adaptive noise cancellation is used as front-end stage to enhance the extracted features for speech recognition under noisy conditions. More specifically, the Constrained Stability Least Mean Square (CS-LMS) algorithm which is a member of the family of adaptive filters has been applied. The Hidden Markov Model based Tool Kit (HTK) is used for training and testing the Automatic Speech Recognizer system. The result obtained shows that the application of adoptive filtering at the front-end enhances the performance of the system in noisy conditions while the CS-LMS algorithm gives the most superior performance among the family of LMS algorithms.

Various physiological parameters help out the plant to overcome the adverse effect of thermal stress. To understand the genetic base of these traits, the current study is a step ahead. The objective of this research was to estimate the gene actions that are responsible for survival of plant under heat stress condition. Six generations (P1, P2, F1, F2, BC1 and BC2) of three crosses were developed by crossing among six cotton genotypes and evaluated at the Central Cotton Research Institute, Multan Farm. The experiment was done in randomized complete blocks besign in three replications under normal and heat stress conditions. The mean of data of all six generations of three crosses were recorded keeping in view the support from literature. Additive, dominance and epistatic genetic effects were operating in controlling the phenotypic expressions of most of the traits contributing to heat stress tolerance. Heterobeltosis for relative water content was observed only in on cross under heat stress condition with the value of 1.39 while the excised leaf water loss did not showed. heterobeltosis under both conditions.

Photography in hazy environment, light attenuation and scattering caused by the water particles present in the medium, result in loss of severe image quality and loss of valuable information. In order to minimize the effect of haze and improve visual quality, this literature present a novel technique combining fuzzy theory, artificial neural networks and image fusion. Transmission map is estimated using fuzzy inference system. Then morphological operation and artificial neural network are applied to remove the halation present. Backpropagation, feedforward, cascaded-feedforward and fitnet artificial neural networks are applied on halation free transmission map for further refinement. Finally, image fusion technique is used to recover an enhanced version of all four images.

Finally, image fusion technique is used to recover an enhanced version of all four images.","PeriodicalId":21859,"journal":{"name":"Sindh University Research Journal","volume":"5 1","pages":"761-766"},"PeriodicalIF":0.0,"publicationDate":"2017-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88878252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
