Penerapan konsep pemanfaatan limbah penggilingan padi sebagai sumber energi dapat mendukung peningkatan produktifitas terbarukan. Konsep eksergoekonomi dijadikan salah satu langkah untuk melihat peluang sekam penambah di sistem yang telah teritegerasi dengan gasifier. Specific Exergy Cost (SPECO) metodenya, dimana metode tersebut menggabungkan analisis eksergi dan ekonomi menerapkan biaya ke da...

Suppose that X is a nonsingular curve over a finite field F. According to ideas of Quillen and others, there is an algebraic K-theory spectrum KX associated to the category of locally free sheaves on X . The word “spectrum” here designates an object in the stable homotopy category of spaces. If X = SpecO is affine, then KX is equivalent to the usual K-theory spectrum associated to the category ...

In the frame of the INCO-Copernicus program of European Commission we have started to develop an audio-visual pronunciation teaching and training method and software system for hearing and speech-handicapped persons to help them to control their speech production. A teaching method is drawn up for progression from the individual sound preparation to practice of the sounds in sentences. The main...

The environmental performance of a combined cooling, heating, and power system is analyzed in this study at component-level using SPECO-based exergoenvironmental analysis. engine consumes natural gas produces 168.6 kW net power. waste heat recovered by LiBr-H2O absorption chiller exchanger, which are used for cooling heating purposes. energy assisted solar field. An Life Cycle Assessment quanti...

Let σ , θ be commuting involutions of the connected reductive algebraic group G, where σ , θ , andG are defined over a (usually algebraically closed) field k, char k = 2. We have fixed point groupsH := G andK := G and an action (H×K)×G → G, where ((h, k), g) → hgk−1, h ∈ H , k ∈ K , g ∈ G. Let G/(H ×K) denote SpecO(G)H×K (the categorical quotient). Let A be maximal among subtori S of G such tha...

Binary geothermal power plants (GPPs) are mostly encountered in fields with medium and low temperatures. The design operation of dual binary GPPs can be difficult due to the fluid properties. This affects their performance feasibility. Thermoeconomics essential elements for GPPs. In this study, advanced exergoeconomic analysis is applied a true GPP (as case study) further evaluate it from econo...

This paper presents exergy and exergoeconomic analysis and parametric study of a Diesel engine based Combined Heat and Power (CHP) system that produces 277 kW of electricity and 282 kW of heat. For this purpose, the CHP system is first thermodynamically analyzed through energy and exergy. Then cost balances and auxiliary equations are applied to subsystems. The exergoeconomic analysis is based ...
