A Novel Approach for Imputation of Missing Value Analysis using Canopy K-means Clustering

Multiple imputation provides a useful strategy for dealing with data sets with missing value. Instead of filling in a single value for each missing value. Imputation is a term that denotes a procedure that replaces the missing values in a data set by some possible values. In this work missing values are being inserted completely at random (MCAR). Dataset taken for this work is heart disease dataset that contains some missing values. The main problem of this k means algorithm to don’t take the random position of the data point, it’s one of the k means for only two way cluster. These multiply imputed data sets are then analyzed by using standard procedures for complete data and combining the results from these analyses. In the proposed method is used for the canopy k-means clustering algorithm using with the predication of higher accuracy calculate the particular data sets. Keywords : missing value, multiple imputation, k-means algorithm and canopy clustering.
Performance Analysis and Enhancement of UTM Device in Local Area Network

Along with the growth of the computer system and networks, the mysterious and malicious threats and attacks on the computer systems are also increasing exponentially. There is a need of continuous evaluation of the security of a network and enhancement of the network attack detection system, which will be able to detect different attacks along with the characteristics of the attacks. In previous work, the port scan attack is considered as precursors to an attack and the target was to provide the mitigation technique for the particular port scan attack. There have been relatively few empirical studies done for port scan related attacks and those that do exist may no longer reflect the impact of such attacks on the functionalities of the UTM/network device and on the network. To address this lack of knowledge, this experiment is carried out in fully controlled test bed environment wherein a set of varieties of attack can be simulated and impact of attack(s) is analyzed and appropriate mitigation technique is suggested to mitigate the port scan attack. The experiment result indicates that the port scan mitigation implementation on UTM helps reducing the load on the UTM device and reduces network congestion effectively.
A Two-step Forecasting Solution and Upscaling Technique for Small Size Wind Farms Located in Hilly Areas of Romania

Taking into account the well-known benefits of using renewable energy as an important energy source, some practical aspects regarding operation must be underlined. In the specific case of wind power plants (WPP) forecasting the generated wind power is the most important issue for assuring stability of Romania’s National Power System (NPS) and economic efficiency of wind power plant operation. The wind power plant operator should report daily to National Dispatching Centre, the hourly energy production for the next day. In case of inaccurate energy production prediction, the National System Operator must take additional measures in order to maintain the stability of NPS. The purpose of our research is to develop a solution, based on Artificial Neural Networks, for forecasting the wind energy production of small output power wind farms located in hilly areas of Romania, thus improving the accuracy of the hourly prediction. The case study is based on two-year historical data for a wind power plant comprising two power production groups situated in Tulcea County, in southeastern Romania. By using this approach, we have also explored the possibility of algorithm generalization, starting from the detailed model of the first production group and generalize it to the second one.
Synthesis and Curing Behaviors ofReactiveCellulose Esters from Renewable Resources

This study deals with synthesis and curing of cellulose esters from renewable resources. Cellulose esters bearing unsaturated groups were prepared from cellulose and fatty acid in LiCl/N,N - dimethylacetamide solution. The subsequent epoxidation produced cellulose esters with oxirane groups in the side chain. Th e resulting cellulose esters were cured by thermal treatment to give transparent films with gloss surface. FT - IR spectrum revealed that reactive groups in the side chains reacted with each other during the reaction to produce cross linked networ k structure . The universal hardness and Young’s modulus of the cross linked cellulose esters increased as a function of the number of reactive groups. The crosslinked cellulose esters also exhibited high glass transition and thermal d ecomposition temperatures. The de velopment of the bio - based material from cellulose and plant oil - based fatty acid would be highly expected to contribute to global sustainability

Association of Ischemic Brainstem Stroke Following Tick Bite and Crimean-Congo Hemorrhagic Fever: A Rare Presentation

Purpose: Crimean-Congo hemorrhagic fever (CCHF) is a viral zoonosis that may be associated with high mortality rate. Several inflammatory mediators (interleukins, IFN-γ, TNF-α etc.) released during disease have been implied in the pathogenesis, which also cause ischemia. Case report: A 60-years old man working in livestock production presented to emergency department with vomiting, fever and impaired balance and gait. In laboratory evaluation, it was found that there was elevation in hepatic enzymes, decreased platelet and leukocyte counts. The patient underwent magnetic resonance (MR) imaging due to gait disorder, revealing restricted diffusion at pons compatible with acute infarct. The patient was admitted with the diagnosis of CCHF and ischemic stroke secondary to infection. During follow-up, no hemorrhage was observed and the patient was discharged as he achieved clinical recovery. Conclusion: In this case report, we discussed ischemic stroke developed secondary to infection in a patient with CCHF and its management in the light of literature.
Identification of rice hybrids using microsatellite and RAPD markers

Having produced a series of hybrid rice varieties especially the first Iranian hybrid rice (IRH1), fingerprinting and genetic purity determination of hybrid seeds were conducted using microsatellite (SSR) and random amplified polymorphic DNA (RAPD) markers. Sixteen rice genotypes including 3 cytoplasmic male sterile (CMS) lines, 5 restorer lines and their 8 hybrid combinations were used in this study. Ten out of fourteen SSR markers produced polymorphic bands in the 16 rice genotypes. The first Iranian hybrid rice, IRH1, could be differentiated from other hybrids possessing a unique SSR fingerprint. Although the SSR markers amplified the unique fingerprints for the restorer lines, they could not differentiate between 2 CMS lines (Neda-A and Nemat-A) and their resultant hybrids. The rice CMS lines and restorer lines could be uniquely identified by RAPD multilocus amplified profile at 7 informative loci. Cluster analysis based on shared alleles and Jaccard’s similarity coefficient using UPGMA algorithm, grouped the rice genotypes into 3 and 4 major clusters according to their microsatellite and RAPD fragment similarities respectively. Non-parental bands were also observed in addition to parental bands which probably correspond to heteroduplex molecules formed by two allelic sequences of different amplified fragments. This demonstrates that heteroduplex bands can be an indicative feature for identifying hybrid individuals.
Methods to Increase Resistivity against Jamming in Selected Types of Optoelectronic Seekers

The paper deals with dilemma of the linear image field of view of the optoelectronic system which is intended for the measurement of the location of remote optical radiation sources. There is a brief description of the lay-out of the detection assemblage and conditions which have to be guaranteed to achieve the pulse position modulation which is needed to the objects detection responsive to the location. The importance of the field of view for jamming resistance and the feasibility of the field of view reduction by the electronic method is explained. This paper also deals with objects discrimination in image data using position prediction. To predict the object position in pictures sequence, principles of Kalman filtration are used. Objects discrimination is realised for matching true and predicted trajectories, when in case of their deviation the object is eliminated.
Upper Tail Large Deviations in First Passage Percolation

For first passage percolation on ℤ2 with i.i. d. bounded edge weights, we consider the upper tail large deviation event, i.e., the rare situation where the first passage time between two points at distance n is macroscopically larger than typical. It was shown by Kesten [24] that the probability of this event decays as exp−Θn2 . However, the question of existence of the rate function, i.e., whether the log‐probability normalized by n2 tends to a limit, remains open. We show that under some additional mild regularity assumption on the passage time distribution, the rate function for upper tail large deviation indeed exists. The key intuition behind the proof is that a limiting metric structure that is atypical causes the upper tail large deviation event. The formal argument then relies on an approximate version of the above which allows us to use independent copies of the large deviation environment at a given scale to form an environment at a larger scale satisfying the large deviation event. Using this, we compare the upper tail probabilities for various values of n. © 2021 Wiley Periodicals LLC.
Effective protection of the sense of hearing is prevented by ISO1999 noise standard

To determine auditory performance in a simple way, pure‐tone audiometry is being used. While health‐related diagnostics is generally becoming more and more refined, ISO1999 is demanding rather rudimentary procedures. Both, frequency range and number of test frequencies are reduced, making it impossible to use modern and effective analytical tools such as pattern recognition. There is a clear relation between pressure‐time‐history of impulses and the details of the resulting auditory damage. But this relation can only be recognized if the restrictions of this standard are being ignored. Typical examples of audiograms from a large data base will be presented, showing simultaneously the data according to ISO1999 and in more modern ways. It will also be demonstrated how useful the tool of pattern recognition can be, for analysis of damages, as well as for preventive measures.
Job Stress and Pyschological Well-Being among Library Employees: A Survey of Library Staff in Selected University Libraries in South-West Nigeria

The study investigated job stress and the psychological well-being of library employees. It closely looked into role predictors of job stress namely, role ambiguity and role conflict as well as physical work environment issues; to determine their relationships on the psychological well-being of library staff in selected University libraries in South-West Nigeria. Survey research design was used for the study. The population consisted of 125 library staff. Sampling was total enumeration so as to accommodate all the library staff. Structured questionnaire was employed for data collection. Data collected were analyzed using frequency, percentage counts and mean. The general findings on job stress revealed that respondents had challenges with technology and excess or quantity of workload. Job stress resulting from role ambiguity was that the respondents were not certain of how much authority they have. As regards role conflict, majority of the respondents stated that it did not cause them any job stress. They also perceived their work environment as stress free. Findings from the hypotheses revealed that role ambiguity, role conflict, and work environment have a positive significant relationship on psychological well-being of the respondents. Based on these findings, this study made some recommendations.

Shark landing recorded by enumerators was used as sampling data daily . This research aim to describ sex ratio, size composition, catch composition of sharks, and length at first maturity. In Banda Aceh, the sharks as target fish collected by sorting the bycatch from tuna longlines and tuna handlines. In Sibolga, sharks is bycatch from fish net, bottom gillnet and purse seine. Overall, there were 20 species of shark caught in west Indian Ocean and landed at those fish landing sites, dominated by Spot tail shark (23%) and Silky shark (13%), whereas Hammerhead shark contributed about 10% and Oceanic whitetip shark was only less than 1%. Almost of Spot tail shark, Silky shark, and Scalloped hammerhead that caught in that area were immature, while for the almost part of Tiger shark and Pelagic thresher were matured. The sex ratios for Spot tail shark, Silky shark, Tiger shark, Pelagic thresher, and Scalloped hammerhead caught and landed at Lampulo and Sibolga fish landing sites were not balance. The length at first maturity for Spot tail shark was Lm=87,1 cm and Lm = 213,2 cm total length for Tiger shark.
The Possibilities of Using High Oil-Sunflower Meal and Enzyme Mixture in Layer Diets

Two experiments were conducted using commercial layers to test the nutritive value of high oil- sunflower meal (HO-SFM) and the efficiency of an enzyme preparation with xylanase, β-glucanase and pectinase activities (Grindazym GP 5000, Danisco Ingredients, Denmark). In the 1 trial, 256 White Hy-Line st layers of 37 wk of age were placed in California type cages. Dietary treatments consisted of 0%, 15%, 20% FE-SFM and 20% FE-SFM+Grindazym GP 5000 (1 g/kg feed) at the expense of full fat soybean and soybean meal. Diets were randomly assigned to each of 4 replicates (4 consecutive cages of 4 layers in each) so as to give each diet to 64 birds according to a completely randomized design. Diets and water were provided to layers ad libitum. Egg production (EP) was recorded daily, and egg weight (EW) and feed intake (FI) on a biweekly base. The second trial was carried out on a commercial layer farm and dietary treatments the same as in the 1 trial were fed to 1477, 1477, 1458 and 1482 layers respectively. Each of the dietary st
G protein-coupled receptor expression and function in Pulmonary Artery Smooth Muscle Cells : : Novel Targets in Pulmonary Arterial Hypertension

Author(s): McDonald, Daniel Scott | Abstract: Pulmonary arterial hypertension (PAH) is characterized by increased pulmonary vascular resistance, in part due to increased proliferation of pulmonary artery smooth muscle cells (PASMC). Since the second messenger 3'5'-cyclic adenosine monophosphate (cAMP) decreases proliferation of PASMC, G protein-coupled receptors (GPCRs) that couple to G[alpha]s are attractive targets for PAH. We used a TaqMan ® GPCR array to identify the GPCRs expressed by PASMC isolated from normal subjects and from patients with PAH. The data revealed that human PASMC express g135 GPCRs, at least 50 of which regulate cAMP formation. We found that GPCR expression correlates with function e.g., of G[alpha]s-coupled GPCRs with formation of cAMP and inhibition of cell proliferation (a functional response to receptor activation), thus documenting that we had identified physiologically relevant GPCRs. Our studies of PAH-PASMC with GPCR arrays revealed that PAH is associated with an increase (g2-fold) in the expression of 41 GPCRs. The greatest increase in GPCR expression was of two orphan receptors, namely GPR113 and GPR75, whose expression was absent in normal PASMC. We also found the mRNA and protein expression of GPR113 and GPR75 were increased in animal models of PAH. Importantly, treatment of PAH-PASMC with a GPR75 antibody blunted the increased proliferation of PASMC and increased cellular cAMP levels. Taken together, the data in this thesis provide evidence that the GPCR microarray can identify GPCRs that contribute to the physiology of PASMC and can uncover new drug targets, such as GPR75 for PAH--a disease that requires therapies beyond those currently in use

The Effects of Non-Farm Business in Rural Sustainable Development: A Case Study in Sanandaj's Rural Areas, Kurdistan

Rural economy has an important role in rural sustainable development in every region or country. However, the rural economy in Iran is too much depending on agriculture and development of other rural economy in particular nonfarm activities, has been neglected by Iranian rural communities. Therefore, the aim of this study was to identify the role of non-farm business on rural sustainable development in Sanandaj Township. This study was a type of surveying research and employed both questionnaire and interview tools. A four-part questionnaire (with 48 questions) was developed in order to collect data from the respondents. Likert-type responses with five scales were used to assess different sections of the questionnaires. The questionnaires’ reliability was tested by Cronbach’s Alpha technique and it was 76% (α= 0.76). A number of 279 families, 181 families with and 98 without non-farm business were selected randomly in 2011. Results of the study showed that non-farm business can contribute to employment growth, income generating, and prevent seasonal and permanent migration from rural areas. Based on the results, non-farm business and non-farm industries need to be strongly invested by financial facilities through rural cooperatives and unions. Additionally, encouraging rural participation is essential in non-farms and industrial activities.
