Characterization of Abattoir Wastewater and Evaluation of the Effectiveness of the Wastewater Treatment Systems in Luna and Kera Abattoirs in Central Ethiopia[ ]


The objectives of this study were characterization of abattoirs wastewater and evaluation of the performance of their wastewater treatment system (WWTS). Samples from untreated effluents of Kera and Luna abattoirs, and treated effluent of Luna abattoir were examined using standard procedure over the duration of two months period of dry season. It was found that extremely high turbidity, color, TS, TSS, BOD5, COD, NH3-N, NO2--N, NO3--N, S-2, SO4-2, PO4-3, TP, FC, TC and FOG. As a result except temperature and pH, the levels of all these parameters of the raw wastewater did not comply with effluent discharge limit of the country. The values of most parameters measured were significantly higher for Kera abattoir than Luna abattoir, at 0.05 significant level of post Hoc ANOVA. The Luna abattoir lagoon, overall percentage removal of the above parameters were 56.67%, 63.22%, 63.77%, 88.68%, 91.59%, 90.91%, -743.08%, 84.33%, 97.7%, 40.76%, 89.19%, -117.43%, -11.43%, 50.41% , 36.30%, and 66.18% respectively which were also not complying with the Ethiopian EPA discharge limit. There is a need of establishment and improvement of abattoir wastewater treatment system, as well as an intervention of regulatory bodies to ensure discharging of high quality treated final effluents by the abattoir industries.

Connectivity Restoration in WSN Using Minimal Topology Changes[ ]


In wireless sensor networks, the efficiency mainly depends on the network connectivity among the nodes as well as coverage of the monitoring area. Failure of nodes due to technical faults or power exhaustion may disturb the existing connectivity by partitioning the network. Node replacement mechanisms are used based on the controlled mobility with the handling of node failures. The idea is to identify the critical nodes which cause the network partitioning and to designate the failure handlers for them suddenly after the network deployment of sensor nodes. To increase the network coverage by identifying the coverage holes and move the mobile nodes to a certain distance. The connectivity restoration process is done using the failure handler with identified movement distance. The effectiveness of the proposed approaches will be validated through simulation experiments.

Explaining the Rights of Foreign Citizens Based on Social Justice: An Analytical Study[ ]


The form of relationships between persons and government is basically recognizable under various terms such as vassal, national or citizen and the quality and quantity of mutual rights and duties of persons and government are also evaluable based on this term. One of the legal resources of public rights and freedoms in Iran is the constitutional law. The Universal Declaration of Human Rights and international covenants can be count as resources. The public freedoms of Iranian citizens is explained as "Rights of Nation" from 19th to 42th articles of constitutional law of Islamic Republic of Iran. In recent centuries, foreign citizens have been entered and resided in Iran due to growing the communication technologies and special geographical and strategic position of Iran in the middle east, such as linking to warm waters of Persian Gulf and Oman sea and having long borders with critical points of the region (e.g., Afghanistan, Iraq, etc). This, in turn, has led to emerge social and security problems. The legal residents with foreign citizenship must have personal, legal and human securities, which declared in the law. By studying the laws in the current research, it was found that the legal residents with foreign citizenship have not enjoyed the equality against law and the current form of citizenship law is not satisfied the current demands and hence, it should be revised. Entering the foreign people to a country, due to any reason, would have political, security, economical, cultural, and geographical and population morphological effects. Particularly, if they were admitting regardless of facilities and demands of the society, the adverse effects induced by presence of them on the vital factors of the country would be more intensive and irrecoverable.

Example Based Machine Translation Using Various Soft-Computing Techniques Review[ ]


This paper focus on the various techniques involved in machine translation (MT).The various techniques involved in machine ignore many aspects when they generate natural language processing (NLP). An optimization technique was one of the major tools for many years in the formulation and solution of computational problems arising in speech and language processing. One of the methods, phrase-based SMT consists of three steps: segmentation of source sentences into a sequence of phrases, translation of each source phrase to a target phrase; and reordering of target phrases into target sentences. Further a Fuzzy Inference system model is used selecting the optimal features from speech vectors. The most fundamental problems in the field of machine learning are Feature selection. Fuzzy logic plays the major role in approximate reasoning. It has the ability to deal with different types of uncertainty, the implementation of the theory to real life problems. A linguistic variable, as its name suggests, is a variable whose values are not numbers but words or sentences in a natural language. Convex optimization problems are formulated and solved, with analytical formulas derived for training the ensemble-learning parameters. The result shows that above mentioned techniques were effective to certain limit which have not yield the proper translation in case of NLP. Thus this paper proposes an idea for under the heading “example based translation using soft-computing tool” like fuzzy logic implementation to yield successful NLP.

Electric Power Transmission and Distribution Losses Overview and Minimization in Pakistan[ ]


Availability of electric power has been the most powerful source for assisting economic, industrial and social developments of any state. Electric power is transferred by means of transmission lines which deliver bulk of power from generating stations to load centers and consumers. Studying the various types of loses uncounted during electrical transmission .The losses are either Technical losses or Non-technical Losses. The technical losses consist of the Corona loss, Joule effect, Magnetic Losses and skin effect. While the Non-technical (commercial ) losses include, theft of electricity, vandalism to electrical substations, poor meter reading, poor accounting and record keeping, etc. For electric power to get to the final consumers in proper form and quality, transmission and distribution losses along the lines must be reduced to the barest minimum.

ECG Trace Digitization Using Image Processing Techniques[ ]


Some of the image processing techniques are developed for an electrocardiogram (ECG) feature extraction and signal regeneration as a digital time series signal. In general the ECG is recorded on a thermal paper which cannot be stored for a long time, because thermal trace over time becomes erased gradually. Some hospitals are saving the ECG thermal papers as scanning images in the electronic equipments (like computers) to maintain medical records, but this method needs to high memory capacity, and use less scanning resolution that gives signal accuracy is less at preview. The main aim of this paper is to extract the 12-lead ECG signals from the thermal paper and converting it to a digital time series signals. Feature extraction and the digital time series signal were tested on 30 of 12-lead ECG paper records from the MIT-BIH arrhythmia database, and the accuracy was between 96.31% and 98.25%. Evaluation of the proposed method for ECG feature extraction was done by comparing the obtained values with manual data and this method offered an accuracy of 98.06%. In addition can be using features extraction to perform an automatic heart disease classification using one of the artificial intelligence methods.

Robust Prediction for Intra and Inter-Handoff (RPIIH) Process[ ]


The overall performance of mobile nodes is mainly affected by the relatively considerable time spent in the handoff process. Most of the time spent is mainly consumed during the authentication process. This process could be even longer especially when the Access Points (AP’s) are busy, which results in delays and/or packets loss. Many handoff techniques have been proposed to shorten the time of authentication however to-date, they have not been fully successful.

The Digitalization of the Walking Stick for the Blind[ ]


Blindness is a state of lacking the visual perception due to physiological or neurological factors. In this project, a simple intuitive blind navigation system is designed and implemented to improve the mobility and safety of blind people during their travels. The prototype includes a wearable glove to help the blind person to navigate alone safely and to avoid any obstacles that may be encountered, whether fixed or mobile, to prevent any possible accident. The main component of this system is the ultrasonic sensor which is used to scan a direction by emitting reflecting ultrasound waves. The reflected ping received from the obstacle is inputted to the microcontroller which is used to determine the distance of the object from the user. This distance then gets outputted by a vibrating motor which vibrates with more intensity as the obstacle gets closer. The current prototype is effective in terms of eliminating the use of a cane and also making it less embarrassing for the user to travel without being noticed.

An Economic Assessment of Nigeria’s Smart Phone Data Bundle Consumption, Subscriber Resource Constraints, and Dynamics. The Case of Abuja & Lagos States.[ ]


This paper examines ways in which smart phone data consumption trends influence demand for airtime data bundles. A model of subscriber response to economic and technical stimuli, conditional on cybernomic and subscriber characteristics, is developed. Three years of survey data, gathered from subscribers of data and voice bundles to evaluate the model empirically. Single SIM smartphones, subscribers are responsive to relative Data Bundle prices and Airtime volume discounts. However, different Data Bundle packages elicit different responses. In particular, some data sharing takes place primarily through subscriber-substitution and intensified smartphone use, while changes in tariff or volume discounts for subscribers having dual SIM smartphones induces frequent and spontaneous network migration. Subscriber and public power constraints bind at different points for different data bundles demand. These results suggest that because multiple data/voice bundle platform interact, subscriber smartphone response coefficient must have multiple strands in order to replace incentives to further bundle demands.

The effect of Garlic treatment on Concentrating Temperature, Potassium Sorbate, Proximate Composition and Sensory properties of Tomato Paste[ ]


Campbell 37 variety of fresh tomato was investigated. These were concentrated at different temperatures of 50OC and 70OC to produce tomato paste. During the concentration to produce paste, garlic at 0.1%w/w, 0.2%w/w and 0.3%w/w concentration and 0.02 and 0.05 potassium sorbate were added. After the production of the tomato paste (treated and the control samples) the proximate analysis was determined. The moisture content of the samples concentrated at 50OC was significantly higher than those of the samples concentrated at 70OC thus, having a moisture content range of 78.19% - 78.67% when compared to the 70OC which is 76.13% - 76.74%. Protein content of the 70OC (11.14-11-20%) concentrated temperature is significantly higher than the protein content of the 50OC (10.67-10.79%) concentrated samples. The ash content of the sample at 50OC treated with 0.1%w/w KS and 0. 2%w/w KS has no significant difference at (P < 0.05). The same trend was observed on the sample at 70OC which are 9.14% and 9.17%. The sensory properties of the samples were evaluated using trained panelist at 9 points hedonic scale. The sample concentrated at 700C, has a low score in the appearance. Potassuim sorbate at both concentration of 0.2 and 0.5 did not affect the aroma and flavour of the sample. Garlic affected the aroma and hence the low score at 700C concentration.

Performance Analysis of Linear Quadratic Regulator Controller Design Techniques for Optimal Servomotor Speed Control[ ]


Time-delays in servomotor speed control arise from inherent time-delays in its state variables or from deliberate introduction of delays into the system for control purposes. Due to the wide application of servomotors in many industrial processes, control of speed is a vital issue and has been of research interest for decades. This heuristic paper therefore presents performance analysis of Linear Quadratic Regulator controller and comparison of its time response matrices in open and closed loop model in servomotor speed control application. The aim is to show that the closed-loop servomotor has better speed control performance rather than its open-loop. It will be shown that Linear Quadratic Regulator method gives better performance, such as steady state error, settling time and overshoot. MatLab/Simulink software will be used to implement all simulations.
