Stack-run adaptive wavelet image compression

We report on the development of an adaptive wavelet image coder based on stack-run representation of the quantized coefficients. The coder works by selecting an optimal wavelet packet basis for the given image and encoding the quantization indices for significant coefficients and zero runs between coefficients using a 4-ary arithmetic coder. Due to the fact that our coder exploits the redundancies present within individual subbands, its addressing complexity is much lower than that of the wavelet zerotree coding algorithms. Experimental results show coding gains of up to 1:4dB over the benchmark wavelet coding algorithm

The Induction and Evaluation of Productive Semidwarf Mutants of Basmati-370

Dry, uniform seeds of Basmati 370 with about 14% moisture content were exposed to 0, 15,20 and 25kR doses of gamma rays (60Co source). Twenty one semi-dwarf mutants were selected from 36,000 M2 plants originating from about 12,000 Ml plants. The breeding behaviour of these mutants was studied in M3 and consequently 6 mutants were selected. The comparative yield test of mutants with mother cultivar Basmati-370, established the high yield potential and semi-dwarf plant posture of mutant strains. The other plant attributes as well as physico-chemical traits of the mutants and parent cultivar are also presented

Studi Eksperimen Pengaruh Dimensi Pipa Kapiler pada Sistem Air Conditioning dengan Pre-Cooling

Penggunaan air conditioner semakin banyak digunakan pada kehidupan sehari-hari diiringi dengan harga jual energi yang semakin mahal. Pada studi eksperimen kali ini mencoba mengoptimalisasi dan menigkatkan efisiensi energi pada sistem air conditioner dengan cara menambahkan satu buah evaporator dan satu buah pre-cooling, dimana pre-cooling dimanfaatkan untuk memanaskan air yang nantinya akan digunakan untuk keperluan rumah tangga. Pada sistem pengkondisian udara yang telah dimodifikasi tersebut maka dilakukan studi eksperimen dengan variasi panjang pipa kapiler, diameter pipa kapiler d=0,054 in, dengan panjang kapiler 1 = 35 cm, kapiler 2 = 65 cm, kapiler 3 = 95 cm. Hasil yang didapat dari studi eksperimen kali ini adalah semakin bertambahnya panjang pipa kapiler, kapasitas pendinginan evaporator, kerja kompresor dan COP dari sistem juga akan semakin kecil dan juga mengakibatkan temperatur masuk evaporator akan semakin kecil, yang akan mengakibatkan efek pendinginan akan semakin besar. Pada variasi pipa kapiler terpendek 35 cm menghasilkan data kapasitas pendinginan total sebesar 2,25 kW, kerja kompresor 0,433 kW, temperatur masuk evaporator 7,26°C, COP sebesar 5,21 dan HRR sebesar 1,16. Sedangkan pada variasi pipa kapiler terpanjang 95 cm kapasitas pendinginan total sebesar 0,72 kW, kerja kompresor 0,332 kW, temperatur masuk evaporator 1,64°C, COP sebesar 4,35 dan HRR sebesar 1,26

The Influence of Product Quality, Prices and Promotions on Interest in Buying Sri Sulastri's Batik

This study aims to determine the effect of product quality, price and promotion of buying interest in Sri Sulastri's Batik of Bantul Yogyakarta. Type of research that used was quantitative research with survey methods. Sample in research was 100 customers who visited the Sri Sulastri's Batik Bantul Yogyakarta. Collection data methods used a questionnaire. Data analysis used multiple linear regression test. The results of the analysis show, 1) the quality of the product has influential positive and significant effect on buying interest in Sri Sulastri's Batik Bantul Yogyakarta, 2) price has positive and significant effect on buying interest in Sri Sulastri's batik Bantul Yogyakarta, 3) promotion has a positive and significant effect on the interest in buying Sri Sulastri's batik Bantul Yogyakarta, 4) coefficient of determination (R2) obtained for 0.536, which means that 53.6% of the product quality, price and promotion variables explain the variance of interest in buying interest, the remaining 46.44% is explained by other variables.Conclusion that product quality, price and promotion have an effect on buying interest Sri Sulastri's Batik Bantul Yogyakarta. Keywords: product quality, price, promotion, buying interes

Analisis Pengukuran Kinerja Perusahaan Dengan Metode Pendekatan Balanced Scorecard (Studi Kasus Pada Koperasi Simpan Pinjam (Ksp) Lohjinawe Rembang)

Performance measurement is used to determine the achievement of corporate objectives of the business unit performance by evaluating the achievement of results that have been achieved through the strategy set. Cooperative is an organization that puts the interests and welfare of members in the central position of the overall activities of cooperatives, in reality, many cooperatives in activities focused on financial factors, including KSP Lohjinawe Rembang. So that the customer and the employees a little neglected. Balanced Scorecard concept is here to help companies determine the extent to which the achievement of performance through four perspectives. This research is qualitative descriptive analysis. Source data used are primary data by questionnaire and in-depth interview to determine the assessment of the translation of the vision, mission and objectives of the company through target setting and weight to key performance indicator (KPI). Secondary data such as financial statements, the development of number of employees and branches of cooperatives in 2013-2015. Performance results are in a healthy position overall with a total score of 92.42 (standard wells 80 <x <100). Obtaining a score on four perspectives that are tailored to the weight of the Balanced Scorecard, financial perspective score was 55.32 (target 60), in the perspective of the customer (member) with a score of 18.25 (target 20), the internal business process perspective score was 10.42 ( target 10) and the last on learning and growth perspective score was 8.24 (target 10). The best performance was in the business process perspective that is able to exceed the target by the achievement of 104.19%. On the financial perspective and the customer perspective attainment results are equally amounted to 92.2%. While learning and growth perspective obtain the lowest achievement results with the percentage of 82.35%
