Let R be a ring and let I 6= R be an ideal of R. Then I is said to be a completely prime ideal of R if R/I is a domain and is said to be completely semiprime if R/I is a reduced ring. In this paper, we introduce a new class of rings known as completely prime ideal rings. We say that a ring R is a completely prime ideal ring (CPI-ring) if every prime ideal of R is completely prime. We say that a...

iran has experienced high food prices in recent years. this paper examines the welfare impacts of rising major food groups' prices on iranian urban households using quadratic almost ideal demand system (quaids) approach. the elasticity coefficients derived from quaids are used to estimate compensated variations (cv).the study uses iranian household expenditure and income survey (heis) raw data,...

In this paper I propose new continuous and discrete choice demand models. To do so, I note that existing demand models from the continuousand discrete-choice demand literatures each have distinct advantages for taking to market-level data. I attempt to build models with the union of the good properties of each literature. For instance, the continuous choice models are more appropriate for disag...

Households consume animal protein after carbohydrate food is fulfilled, moreover prices are increasing. This study aims to analyze the effect of rising beef on demand. The demand system approach uses Quadratic Almost Ideal Demand System (QUAIDS) model. Estimation parameters using Iterated non-linear Seemingly Unrelated Regression. research data use 2016 National Socio-Economic Survey (Susenas, ...

The paper aims to estimate the food demand of rural households in Bengkulu Province, Indonesia, using Quadratic Almost Ideal Demand System (QUAIDS) and microdata from SUSENAS. We aggregate into five groups: staple food, animal vegetables & fruits, prepared other food. results show that for is most sensitive expenditure, whereas expenditure-inelastic. Staple are substitutes each other. O...

Advisor: Azzeddine Azzam While technically considered as fungi, mushrooms are often classified as vegetables because they provide many of the nutritional attributes of produce as well as meat, beans, and grains. The U.S. is the largest consumer of mushrooms and the share of imports in total consumption of mushrooms has been rising and will likely continue to The contribution of this thesis is t...

Employing the ultrafast control of electronic states a semiconductor quantum dot in cavity, we introduce novel approach to achieve on-demand emission single photons with almost perfect indistinguishability and photon pairs near ideal entanglement. Our scheme is based on optical excitation off-resonant cavity mode followed by using time-dependent quantum-confined Stark effect, which then allows ...

Based on the panel data of 306 cities in China from 2002 to 2012, this paper investigates China's road transport fuel (i.e., gasoline and diesel) demand system by using the Almost Ideal Demand System (AIDS) and the Quadratic AIDS (QUAIDS) models. The results indicate that own-priceelasticitiesfordifferentvehiclecategoriesrangefrom-1.215to-0.459(byAIDS)andfrom -1.399 to-0.369 (by QUAIDS). Then, ...
