"Computation and storage in the cloud is the first comprehensive and systematic work investigating the issue of computation and storage trade-off in the cloud in order to reduce the overall application cost. Scientific applications are usually computation and data intensive, where complex computation tasks take a long time for execution and the generated datasets are often terabytes or petabytes in size. Storing valuable generated application datasets can save their regeneration cost when they are reused, not to mention the waiting time caused by regeneration. However, the large size of the scientific datasets is a big challenge for their storage. By proposing innovative concepts, theorems and algorithms, this book will help bring the cost down dramatically for both cloud users and service providers to run computation and data intensive scientific applications in the cloud. Covers cost models and benchmarking that explain the necessary tradeoffs for both cloud providers and users. Describes several novel strategies for storing application datasets in the cloud. Includes real-world case studies of scientific research applications."

"Data dari International Association of Refrigerated Warehouse (IARW) mengeluarkan laporan kapasitas cold storage, dimana India menduduki puncak kapasitas terbesar dengan kapasitas 131 juta meter kubik, yang kemudian disusul oleh Amerika dengan kapasitas 115 juta meter kubik Indonesia dibanding dengan Negara lain seperti India, Amerika,masih tertinggal jauh dengan kapasitas cold storage sebanyak 200 ribu meter kubik. Maka dari hal tersebut Indonesia masih perlu memperluas dan memperbanyak perusahaan penyedia jasa cold storage untuk membantu menangani permintaan kebutuhan cold storage yang terus meningkat. Contoh nya ada beberapa perusahaan di Indonesia seperti PT Adib Cold Logistics yang menyediakan beragam layanan kontrol suhu seperti cold storage dan chiller. Dilengkapi dengan sistem pendingin Mayekawa Newton terbaru yang aman untuk lingkungan dan menghasilkan suhu yang stabil dalam rentang -25˚C hingga +25˚C. Akan tetapi setiap perusahaan yang menyediakan jasa pendinginan, terutama yang menggunakan cold storage pasti akan mengeluarkan biaya untuk melakukan kegiatan maintenance. Terdapat beberapa faktor yang akan mempengaruhi biaya maintenance perusahaan, yang paling utama adalah sistem refrigerasi yang digunakan. Karena dari sistem refrigerasi yang digunakan perlu dilakukan pengecekan dan perbaikan berkala, terhadap komponen sistem refrigerasi seperti kompresor, kondensor dan evaporator. Untuk menghitung nya ,diusulkan perhitungan mengenai perhitungan beban pendingin, kapasitas pendingin dengan diagram psikometri dan perhitungan COP untuk dibandingkan dengan spesifikasi dari sistem pendingin Mayekawa Newton.Studi ini membahas mengenai apakah PT.Adib Cold Logistic sudah berjalan sesuai dengan spesifikasi alat Mayekawa Newton dalam mendinginkan cold storage nya.

ata from the International Association of Refrigerated Warehouse (IARW) has released a report on cold storage capacity, where India ranks first with the largest capacity of 131 million cubic meters, followed by the United States with a capacity of 115 million cubic meters. Compared to other countries like India and the United States, Indonesia is still far behind with a cold storage capacity of only 200,000 cubic meters. Therefore, Indonesia still needs to expand and increase the number of cold storage service providers to help meet the increasing demand for cold storage. An example of such companies in Indonesia is PT Adib Cold Logistics, which provides various temperature control services such as cold storage and chiller. Equipped with the latest Mayekawa Newton cooling system that is environmentally friendly and produces stable temperatures ranging from -25˚C to +25˚C. However, every company that provides cooling services, especially those using cold storage, will incur costs for maintenance activities. There are several factors that will affect the maintenance costs of a company, with the most important one being the refrigeration system used. Because periodic checks and repairs need to be carried out on components of the refrigeration system such as compressors, condensers, and evaporators. To calculate these costs, it is proposed to calculate the cooling load, cooling capacity using psychrometric charts, and COP calculations to compare them with the specifications of the Mayekawa Newton cooling system. This study discusses whether PT Adib Cold Logistics operates according to the specifications of the Mayekawa Newton equipment in cooling its cold storage. In this study, calculations are made for the cooling load on product load, lighting load, personnel load, electrical load, material load, and infiltration load. Cooling capacity is also calculated using psychrometric charts from the p-h diagram. The methodology used is quantitative and experimental. The quantitative method involves collecting data directly from PT Adib Cold Logistics. The analytical method focuses on calculating the cooling load and cooling capacity according to applicable formulas. Based on the study results, it was found that the cooling load can be reduced by 4,27 kW by implementing the improvements provided by the author, resulting in a cost savings of Rp.53.299.028 within a one-year period."
