Greening cloud-enabled big data storage forensics : Syncany as a case study

The pervasive nature of cloud-enabled big data storage solutions introduces new challenges in the identification, collection, analysis, preservation and archiving of digital evidences. Investigation of such complex platforms to locate and recover traces of criminal activities is a time-consuming process. Hence, cyber forensics researchers are moving towards streamlining the investigation process by locating and documenting residual artefacts (evidences) of forensic value of users’ activities on cloud-enabled big data platforms in order to reduce the investigation time and resources involved in a real-world investigation. In this paper, we seek to determine the data remnants of forensic value from Syncany private cloud storage service, a popular storage engine for big data platforms. We demonstrate the types and the locations of the artefacts that can be forensically recovered. Findings from this research contribute to an in-depth understanding of cloud-enabled big data storage forensics, which can result in reduced time and resources spent in real-world investigations involving Syncany-based cloud platforms

Planting Design Expression on Students Perceiving Campus Landscape Quality

Planting design plays a vital role in evaluating and enhancing landscapes by deliberately arranging and selecting plants within a given area. It encompasses various elements, including plant types, arrangement, density, colour, texture, and composition, all contributing to the visual appeal and aesthetics of green spaces, creating harmonious and visually pleasing environments. Beyond environmental sustainability, planting design also holds significance in promoting aesthetical value for certain spaces. This study focuses on exploring how different planting design approaches impact the students’ expression when perceiving quality of campus green spaces. The objectives are to identify preferences for planting design scenes and investigate the influencing criteria. A Likert-scale questionnaire utilizing 51 planting images from Universiti Putra Malaysia is employed to collect data. The gathered preferences are analysed using IBM SPSS Statistics 23 to determine significant criteria and expression on preferences. The findings emphasize students' preferences for coherent and balance plant arrangements, naturalness with moderate density and maintenance. The implications of this study will aid campus designers in developing future landscape designs that incorporate preferred planting design characteristics

This research is an extension of previous researchers about wind catcher using computational fluid dynamic (CFD). The previous research did not use baffle variations. The aim of the research work was to compare two type ability of wind catcher in obtaining optimum mass flow rate. The first type was wind catcher was designed without baffle and second type was wind catcher designed using baffle that consisted of; wind catcher with cylinder baffle, square baffle, plus with four holes baffle, and combined wind catcher with eight holes baffle. Simulation was carried out in vary of incoming wind speed of 0.5m/s to 5m/s at 11,5m height. Due to the complexity of geometry then unstructured mesh was adopted. The wind catcher without baffle resulted total element of 1237341, whereas, wind catcher with cylinder baffle resulted in 2090432 element, square baffle resulted element of 2366514, baffle plus resulted in element of 4425278, and combined baffle produced element of 7747840. Initially, The k-epsilon turbulen model was selected in this simulation as it is robust in time. The parametric study of wind catcher model was carried out in two steps; the first step was comparing performa of five shape of wind catcher. Where, the wind catcher with four holes with plus baffle resulting optimum mass flow rate, and the second performance was demonstrated by studying effect of extension baffle. In this study, wind catcher was modified by extending baffle of 1m. Result of the comparison study showed that wind catcher with one extension baffle resulted an optimal performance. Further simulation was by investigating different inflation boundary layer and different turbulen model. In studying inflation boundary layer, total maximum of layer was varying from: 5, 10, 15, dan 20 at wind speed of 5 m/s. The optimum performance was reached by maximum layer of 10. The study of turbulence model was carried out at all simulation involved k-epsilon, Shear Stress Transport, BSL Reynold Stress, dan SSG Reynold Stress turbulence model. The wind speed was set as same as in studying inflation boundary layer of 5 m/s. The Studi showed that SSG Reynold Stress turbulen model was able to reach an optimum performance. All simulation was carried out using ANSYS,version 15.0

Setting research priorities to improve global newborn health and prevent stillbirths by 2025.

BACKGROUND: In 2013, an estimated 2.8 million newborns died and 2.7 million were stillborn. A much greater number suffer from long term impairment associated with preterm birth, intrauterine growth restriction, congenital anomalies, and perinatal or infectious causes. With the approaching deadline for the achievement of the Millennium Development Goals (MDGs) in 2015, there was a need to set the new research priorities on newborns and stillbirth with a focus not only on survival but also on health, growth and development. We therefore carried out a systematic exercise to set newborn health research priorities for 2013-2025. METHODS: We used adapted Child Health and Nutrition Research Initiative (CHNRI) methods for this prioritization exercise. We identified and approached the 200 most productive researchers and 400 program experts, and 132 of them submitted research questions online. These were collated into a set of 205 research questions, sent for scoring to the 600 identified experts, and were assessed and scored by 91 experts. RESULTS: Nine out of top ten identified priorities were in the domain of research on improving delivery of known interventions, with simplified neonatal resuscitation program and clinical algorithms and improved skills of community health workers leading the list. The top 10 priorities in the domain of development were led by ideas on improved Kangaroo Mother Care at community level, how to improve the accuracy of diagnosis by community health workers, and perinatal audits. The 10 leading priorities for discovery research focused on stable surfactant with novel modes of administration for preterm babies, ability to diagnose fetal distress and novel tocolytic agents to delay or stop preterm labour. CONCLUSION: These findings will assist both donors and researchers in supporting and conducting research to close the knowledge gaps for reducing neonatal mortality, morbidity and long term impairment. WHO, SNL and other partners will work to generate interest among key national stakeholders, governments, NGOs, and research institutes in these priorities, while encouraging research funders to support them. We will track research funding, relevant requests for proposals and trial registers to monitor if the priorities identified by this exercise are being addressed

Kebangkitan Kesultanan Ternate pada Era Reformasi 1998-2002

 The elite revival of the Ternate Sultanate after the New Order illustrated how the palace group played a new role in staying in its position as a clan of power in the local sphere. In this case, the emergence of the elite of the Ternate Sultanate can be understood and interpreted in three respects. First, the rise of feudalistic power in the region to strengthen political position stemmed from cultural construction based on history and genealogical similarities. Second, the individual revival of the Sultan of Ternate MudafarSyah in the name of the Sultanate institution as his political vehicle. Third, there is the elite desire of the Ternate Sultanate to be more institutionally accommodated into the formal government political stage. This reality shows the political participation of the Ternate Sultanate in the post-independence domain of local politics until now, is an important field of historical research. As a historical phenomenon, the process of dynamics of local politics like this is interesting to study, because the Sultan of Ternate has long been a part of the history of politics in North Maluku. Also, there is an implicit message about how partial Indonesian political studies are if they only focus on the dynamics of national politics. In the case, there are several national political issues which can initially be pursued from the region and vice versa Kebangkitan elite Kesultanan Ternate pasca-Orde Baru mengambarkan bagaimana kelompok istana memainkan peran baru agar tetap berada pada posisinya sebagai pengenggam kekuasaan di ranah lokal. Dalam hal ini, apat dipahami bahwa ada tiga faktor yang menyebabkan kemunculan elit Kesultanan Ternate Pertama, bangkitnya kekuasaan feodalistik di daerah untuk memperkuat posisi politik bersumber dari konstruksi budaya yang berbasiskan pada sejarah masa lalu maupun kesamaan genealogis. Kedua, kebangkitan secara individual Sultan Ternate Mudafar Syah dengan mengatasnamakan institusi kesultanan sebagai kendaraan politiknya. Ketiga, adanya keinginan elite Kesultanan Ternate untuk lebih diakomodasikan secara institusional ke dalam panggung politik pemerintahan formal. Realitas  tersebut menunjukkan  partisipasi politik  Kesultanan Ternate dalam ranah politik lokal pasca-kemerdekaan hingga kini, merupakan sebuah bidang penelitian sejarah yang penting. Sebagai sebuah fenomena historis, proses dinamika politik lokal seperti ini menarik untuk diteliti, karena telah sejak lama para Sultan Ternate menjadi bagian dalam sejarah perpolitikan di Maluku Utara. Selain itu,  ada sebuah pesan implisit tentang betapa parsialnya kajian politik Indonesia bila hanya memfokuskan pada dinamika politik nasional saja. Pada hal ada beberapa persoalan politik nasional yang awalnya dapat diruntut  dari daerah dan begitu pula sebaliknya
