    Resource optimization in energy constrained real-time adaptive embedded systems highly depends on accurate energy and throughput estimates of processor peripherals. Such applications require lightweight, accurate mathematical models to profile energy and timing requirements on the go. This paper presents enhanced mathematical models for data cache energy and throughput estimation. The energy and throughput models were found to be within 95% accuracy of per instruction energy model of a processor, and a full system simulator?s timing model respectively. Furthermore, the possible application of these models in various scenarios is discussed in this paper

Dari hasil penelitian ini dapat disimpulkan bahwa kinerja reproduksi sapi Aceh baik, rataan umur kawin pertama adalah 16,6 bulan , jarak beranak,15,3 bulan, pedet disapih pada umur 5,3 bulan dan umur kawin kembali setelah beranak 6,4 bulan. Kata kunci: Karakteristik reproduksi, sapi potong lokal, umur kawin pertama, jarak beranak, umur penyapihan pedet dan umur kawin kembali setelah beranakAbstract. This study aims to determine the characterization of reproductive performance of local beef cattle. This study was conducted in subdistrict of Jantho, Aceh Besar districk of Aceh Province covering five villages of desa Jantho Makmur, Desa Baroh, desa Terben,desa Jalin, desa Trans Jalin. The study was conducted for one month (March 1 to March 31, 2018). Survey method was used in this research. Determination of respondent is by using method of Purposive Sampling that is taking sample with minimum requirement of breeder to keep one local beef cattle that have gave birthtwo times. As the respondents set as many as 20 farmers. From the results can be concluded that the performance of local beef cattle reproductive is good, average age of first mating is 6,4 month, calving interval 15,3 month, calf weaned at age 5,3 month, age of remating after calving 6,4 bulan. Keywords: Reproductive performance, local beef cattle, age of first mating, calving interval, calf weaned and remating after calvin

    Penelitian ini menganalisa tentang pemilihan pompa alat penukar kalor Shell dan Tube kapasitas Skala Laboraturium. Pompa yang digunakan dalam sistem Shell and Tube Heat exchanger ini menggukan dua jenis pompa , yaitu : pompa sentrifugal untuk distribusi air dingin dan pompa oli atau Gear Pump untuk distribusi oli panas (fluida panas).Heat Exchanger atau Alat Penukar Kalor merupakan suatu alat untuk memindahkan energi termal dari sumber panas ke sumber yang lebih dingin, atau alat yang memungkinkan terjadinya perpindahan energi kalor atau panas antara dua fluida atau lebih yang mempunyai temperatur berbeda. Oleh sebab itu perlu adanya anilisa pemilihan pompa yang tepat agar sistem beropersi dengan maksimal.Dalam perancangan ini aspek-aspek yang perlu dihitung antara lain : Menentukan kapasitas Heat Exchanger sehinnga bisa diketahui kebutuhan aliran air yang dibutuhkan untuk mendinginkan fluida panas, sehingga effisiensi dari Heat exchanger bisa mencapai nilai maksimal

    The Impact of Spatial Masking in Image Quality Meters

    Get PDF
    Compression of digital image and video leads to block-based visible distortions like blockiness. The PSNR quality metric doesn2019;t correlate well with the subjective metric as it doesn2019;t take into consideration the impact of human visual system. In this work, we study the impact of human visual system in masking the coding distortions and its effect on the accuracy of the quality meter. We have chosen blockiness which is the most common coding distortion in DCTbased JPEG or intracoded video. We have studied the role of spatial masking by applying different masking techniques on full, reduced and no reference meters. As the visibility of distortion is content dependent, the distortion needs to be masked according to the spatial activity of the image. The results show that the complexity of spatial masking may be reduced by using the reference information efficiently. For full and reduced reference meters the spatial masking hasn2019;t much importance, if the blockiness detection is accurate, while for the no reference meter spatial masking is required to compensate the absence of any required reference information

    Phytic acid: How far have we come?

    Phytic acid is a major storage form of phosphorous. Obvious reasons are there to favor its reduced concentration in organisms. However, certain justifications can also be settled, in order to support its increased natural concentration. In both cases, there are questions to be answered to favor one side while alleviating the harm of neglecting the other. This article reviews our current state of understanding of phytic acid - focusing on the topics of current and future interests in the field

    Characterization of transport and magnetic properties in thin film La(0.67)(Ca(x)Sr(1-x))(0.33)MnO(3) mixtures

    Full text link
    We have grown thin films of (100) oriented La_{0.67}(Ca_{x}Sr_{1-x})_{0.33}MnO_{3} on (100) NdGaO_{3} substrates by off-axis sputtering. We have looked at the changes in the resistivity and magnetoresistance of the samples as the Ca/Sr ratio was varied. We find that as the calcium fraction is decreased, the lattice match to the substrate decreases, and the films become more disordered, as observed in transport measurements and the variation in Curie and peak resistance temperatures. We find a correlation between the temperature independent and T^2 terms to the low temperature resistivity. The room temperature magnetoresistance exhibits a maximum as the peak temperature is increased by the substitution of Sr for Ca, and a change in the field dependence to the resistivity at room temperature is observed.Comment: 5 pages, 6 eps figures, to be published in Journal of Applied Physic
