Dimensionality Reduction Approach using Attributes Extraction and Attributes Selection in Gene Expression Databases
Get PDFThe gene expression databases are formed by a high number of attributes. To deal with this amount, data dimensionality reduction is used in order to minimize the volume of data to be treated regarding the number of attributes, and to increase the generalization capability of learning methods by eliminating irrelevant and/or redundant data. This paper proposes an approach to means of dimensionality reduction, which joins attribute extraction and attributes selection. For this, we used the Random Projection method and the filter and wrapper approaches for the attribute selection. The experiments are realized in five gene expression microarray databases. The results of the experiments showed that join of those approaches can provide promising results
A Rare Case of Mesenteric Trauma after a Clandestine Abortion in Morocco
Get PDFIn Morocco abortion is illegal; this is why the termination of pregnancy is performed in unsafe conditions which may lead to uterine perforation, mesenteric trauma, uncontrolled hemorrhage and even death. The small bowel is the most commonly injured due to its pelvic location and mobility. We report a case of 28-year-old nulliparous married female who presented to the emergency department after a failed abortion procedure. We performed haemostatic suture of the uterine lesion then resection of the injured distal bowel, and then a stoma was confected. The patient was discharged after 2 weeks of hospitalisation .Three months later; the stoma reversal surgery was done without complication. This case underlines the need for a regulation of a safe abortion in the world
Practical and Symbolic Aspects of Olive Oil Donations in Asia Minor during the Hellenistic period and the Principate
Get PDFThis paper concludes some major aspects regarding olive oil donations in Asia Minor during the Hellenistic period and the Principate. These benefactions were part of the larger phenomenon called Euergetism, that took place in all Greek cities, starting with the fifth Century BC, in which rich and poor, magistrates and ordinary people were exchanging gifts and honors for the well-being of the City and for themselves. Through the study of oil donations there can be highlighted the relations between donor and donated, the importance of the value of gifts in receiving honors, the social and economic characteristics of the city during the studied period, the practical and symbolic aspects that derive from donating olive oil in antic Asia Minor
Upgrading of an Extended Aeration System to Improve Wastewater Treatment
Get PDFAccording to this study, an extended aeration system can be upgraded by adding surface turbine aerators to the tanks and building new primary sedimentation tanks. Moreover, the biochemical oxygen demand (BOD5), chemical oxygen demand (COD), and total suspended solids (TSS) were also observed to be 440, 682, and 212 mg/L after primary settling, respectively. These values represent the removal of about 35% of the organic load and about 68% of the suspended solids, which reduces the organic load and sediments entering the secondary treatment. Furthermore, effluent BOD5, COD, and TSS values were 30, 47, and 32 mg/L respectively, while those permitted values are 60 mg/L of BOD5, 80 mg/L of COD, and 50 mg/L of TSS reflecting the success of the upgrading work
The Users’ Body and Their Digital Representation in Interactive Installation- a Mereological Perspective
Get PDFThis article examines the relationship between the users’ body and its digital representations in digital body interactive installations, a sub-category of digital interactive art. Due to the reflective capacity of the interfaces incorporated in these artworks, the researchers designate the connection between the body and its digital embodied image as identification, or self- identification, terms which are not contextualized and detailed, leading to theoretical misinterpretations. To approach the problem, we use an ontological branch of study- mereology, and we discuss the membership of the body within the interactive system and the connection between the users’ body and the digital embodied self: component-integral relationship, functional, mandatory, and configurational, separation, encapsulation, and exchange relationships. Afterwards, we use the composition as identity thesis to show that instead of identification or self-identification, we characterize the connection between the users’ body and the digital body as “partial, temporary and stationary exchange” based on active engagement, self- consciousness, and body awareness. The relevance and novelty of the article tackle two directions: first, the interdisciplinary combination of logical philosophy and digital art, and secondly, the lack of ontological explanations regarding the structural relations in digital interactive art
Scaling Up Manufacturing of Edible Coatings for Food
Get PDFOne of the most important methods for prolonging the shelf life of fruits and vegetables is edible coatings. The manufacture of the edible coating was tested in the laboratory before being scaled up to the industrial scale which is a procedure for applying, which applies the same process to different output volumes. One of the most crucial processes in the manufacturing of edible coatings is mixing. The equipment needed to scale up the production of edible solutions for food coating was also assessed. The results of the measurements revealed that scaling up mixing is based upon constant power/volume, equal blend duration, and adjusting the impeller/tank (D/T) diameter ratio was possible. A four-blade impeller was utilized to homogenize 1% carrageenan solutions at 70°C. Also, mixing parameters (Power number, Blend number, and Pumping number) were determined at different D/T ratios. Cost-effective pipe diameter and optimum pipe diameter per unit length were also determined
Influence of Socio-demographic Variables on Prevalence of Hypertension in Lahore Division, Pakistan
Get PDFHypertension is a growing public health issue at global level and it is considered as a potent factor for cardiovascular ailments. But various socio-demographic factors are root causes to provoke this physiological disorder. In current study, through cross sectional survey, performa based data of 100 persons was collected from cities Lahore division, Pakistan. The results showed that males are more suffering than females and fall in age range of 20-40yrs. Most frequently reported initial symptoms are fatigue, irregular heartbeat and difficulty in breathing. Whereas district wise comparison indicated higher prevalence level in Lahore and Kasur than Shiekhupura and Nankana Sahib. Similarly, ANOVA results highlighted that economic status matters the most, parallel to the extent of awareness among masses, that’s why; mediocre is suffering more than upper or lower class. Thus cost effective treatments based findings should be our future goal to control this growing disease
BER and Capacity/Spectral Efficiency Enhancement of MIMO Systems Using Digital Antenna Arrays Beamforming
Get PDFMulti-input Multi-output (MIMO) systems are of the most promising ones in the field of wireless communications as they provide high data rates and reduce the bit error rate (BER) using spatial multiplexing (SM) and diversity gain techniques, respectively. The deep review of MIMO systems shows that most of them are based on the utilization of uniform linear antennas (ULA) arrays. For further performance enhancement, a new digital array beamforming technique for linear antenna arrays optimization is introduced for both single-user and multi-user MIMO systems to achieve maximum gain. In our proposed technique, the antenna arrays are implemented for a higher gain by adjusting the feeding and the distance between the antenna elements. The modified mathematical model for our proposed digital array beamforming MIMO system has been derived and merged to the current linear detection techniques such as Maximum Likelihood (ML), Zero Forcing (ZF), and Minimum Mean Square Error (MMSE). The simulation results demonstrated the superiority of our proposed technique over the traditional MIMO systems in terms of BER and spectral efficiency (SE)
A Survey on Botnet Attacks
Get PDFDevices connected to the Internet are the target of numerous attacks to steal or exploit their resources. As these attacks become widespread (and sophisticated), the first step in protecting your organization is knowing exactly what you are facing. We currently have botnets that are the main source of network attacks such as spam, denial of service (DDoS), click fraud, data theft, Pass the Hash, and RDC attack. With the evolution of technology, we have several solutions to protect against attacks that undermine businesses, governments, individuals, but security attack methods are increasing daily. This study seeks further investigate botnet attacks and also provide a comparison of these attacks, lastly, the survey will create awareness for forthcoming botnet research endeavors
