Classification and Performance Study of Task Scheduling Algorithms in Cloud Computing Environment

Cloud computing is becoming very common in recent years and is growing rapidly due to its attractive benefits and features such as resource pooling, accessibility, availability, scalability, reliability, cost saving, security, flexibility, on-demand services, pay-per-use services, use from anywhere, quality of service, resilience, etc. With this rapid growth of cloud computing, there may exist too many users that require services or need to execute their tasks simultaneously by resources provided by service providers. To get these services with the best performance, and minimum cost, response time, makespan, effective use of resources, etc. an intelligent and efficient task scheduling technique is required and considered as one of the main and essential issues in the cloud computing environment. It is necessary for allocating tasks to the proper cloud resources and optimizing the overall system performance. To this end, researchers put huge efforts to develop several classes of scheduling algorithms to be suitable for the various computing environments and to satisfy the needs of the various types of individuals and organizations. This research article provides a classification of proposed scheduling strategies and developed algorithms in cloud computing environment along with the evaluation of their performance. A comparison of the performance of these algorithms with existing ones is also given. Additionally, the future research work in the reviewed articles (if available) is also pointed out. This research work includes a review of 88 task scheduling algorithms in cloud computing environment distributed over the seven scheduling classes suggested in this study. Each article deals with a novel scheduling technique and the performance improvement it introduces compared with previously existing task scheduling algorithms. Keywords: Cloud computing, Task scheduling, Load balancing, Makespan, Energy-aware, Turnaround time, Response time, Cost of task, QoS, Multi-objective.

Menakar RUU Kkg Dari Perspektif Kajian Hukum Islam

The Draft Law on Gender Equality is an early draft at the socialization stage, still to receive inputs from the society. However, there have been many negative responses and many Islamic groups reject it wholesale. Their argument interalia, is that the draft law is secular in nature and is thus contradictory to fundamentalist Islamic teachings and law. This article will attempt to discuss and position the draft law within the ambit of Islamic law. The general conclusion is that while most of the ideas contained within the draft law is much in line with the principles of Islamic law, several articles which conflict with Islamic law need to be revised and changed. The shortcomings and errors within the draft law are indeed in need of criticism, but it should not be a reason to reject the entire draft la

Minoritas Yang Terlindungi: Tantangan Dan Kontinuitas Gkjw Jemaat Mojowarno Di Kota Santri Jombang

Tulisan ini membahas perihal hak kebebasan beragama dan berkeyakinan GKJW Jemaat Mojowarno Jombang. Mojowarno pada mulanya adalah desa Kristen dan tidak mengizinkan umat non-Kristiani tinggal dan menetap di desa itu. Desa ini pula pernah menjadi pusat penyebaran Kristen Protestan di Jawa Timur. Pertumbuhan penduduk memaksa Mojowarno menjadi desa yang terbuka bagi pemeluk agama lain. Berdasarkan statistik tahun 2011, pemeluk agama Kristen Protestan di Jombang hanya sekitar 1,2%, termasuk GKJW Jemaat Mojowarno. Sebagai kelompok minoritas, Jemaat GKJW Mojowarno mempunyai kerentanan atas tindakan intoleransi dan pelanggaran hak kebebasan beragama dan berkeyakinan. Sekalipun berada di tengah-tengah mayoritas Islam, hak kebebasan beragama dan berkeyakinan GKJW Jemaat Mojowarno tetap terpelihara dan terjamin. Komitmen individu atau kelompok yang mendorong sikap dan perilaku mereka dalam mewujudkan kehidupan bersama secara harmonis dan rukun dalam masyarakat Mojowarno. Mereka larut dalam kehidupan sosial, tetapi tidak hanyut dalam agama dan keyakinan yang berbeda. This paper discusses about the right to freedom of religion and belief GKJW Church Mojowarno Jombang. Mojowarno in the beginning was a Christian village, and do not allow non-Christians to stay and settle in the village. The village was also to be center of the spread of Protestant Christians in East Java. Population growth forced the village Mojowarno be open to other faiths. Based on the statistics of 2011, Protestant faiths in Jombang only about 1.2%, including GKJW Mojowarno Church. As a minority group, the Church has a vulnerability GKJW Mojowarno on acts of intolerance and violations of the right to freedom of religion and belief. Even being in the middle of the Moslem majority, the right to freedom of religion and belief GKJW Mojowarno congregation to be maintained and guaranteed. The commitment of individual or groups that encourage their attitudes and behavior in realizing life together in harmony and harmonious society Mojowarno. They dissolve in social life, but it does not drift in different religion and belief

Microbiome profile associated with malignant pleural effusion.

INTRODUCTION:There is ongoing research into the development of novel molecular markers that may complement fluid cytology malignant pleural effusion (MPE) diagnosis. In this exploratory pilot study, we hypothesized that there are distinct differences in the pleural fluid microbiome profile of malignant and non-malignant pleural diseases. METHOD:From a prospectively enrolled pleural fluid biorepository, samples of MPE were included. Non-MPE effusion were included as comparators. 16S rRNA gene V4 region amplicon sequencing was performed. Exact Sequence Variants (ESVs) were used for diversity analyses. The Shannon and Richness indices of alpha diversity and UniFrac beta diversity measures were tested for significance using permutational multivariate analysis of variance. Analyses of Composition of Microbiome was used to identify differentially abundant bacterial ESVs between the groups controlled for multiple hypothesis testing. RESULTS:38 patients with MPE and 9 with non-MPE were included. A subgroup of patients with metastatic adenocarcinoma histology were identified among MPE group (adenocarcinoma of lung origin (LA-MPE) = 11, breast origin (BA-MPE) = 11). MPE presented with significantly greater alpha diversity compared to non-MPE group. Within the MPE group, BA-MPE was more diverse compared to LA-MPE group. In multivariable analysis, ESVs belonging to family S24-7 and genera Allobaculum, Stenotrophomonas, and Epulopiscium were significantly enriched in the malignant group compared to the non-malignant group. CONCLUSION:Our results are the first to demonstrate a microbiome signature according to MPE and non-MPE. The role of microbiome in pleural effusion pathogenesis needs further exploration

Kontekstualisasi Pemikiran Kh. Hasyim Asy'ari Tentang Persatuan Umat Islam

: The Contextualization of KH. Hasyim Asyari's View on the Muslim Unity. The Muslim unity is a logical consequence of religious teachings concerning the Muslim brotherhood (ukhuwah Islamiyâh). The diversity of the Muslim community has become a challenge for its application. In Indonesian, the diversity of mainstream school of thoughts, organizations, and parties have given rise to disintegration of the Muslim society. The internal conflicts that come out from various reasons is an evident of that disintegration. This paper analyzes KH. Hasyim Asyari's view concerning the Muslim unity. The authors find that the idea of the Muslim unity should be based upon faith and anti-fanatism. It reflects the concordance of faith and could be realized in anti-fanatism attitude in the Muslim society. The idea of KH Hasyim Asy`ari is perceived of utmost important, for it may become an alternative solution for the social problems
