Guillain-Barré syndrome (GBS) is an autoimmune reaction that can cause acute neuromuscular paralysis. Of an estimated 2,628 to 9,575 new U.S. cases with GBS annually, 526 to 3,830 are triggered by infection with Campylobacter, the most frequently isolated cause of foodborne diarrhea. Estimated total annual costs of Campylobacter-associated GBS of $0.2 to $1.8 billion plus previously estimated c...

Connection of electric storage technologies to smartgrids will have substantial implications for building energy systems. Local storage will enable demand response. When connected to buildings, mobile storage devices such as electric vehicles (EVs) are in competition with conventional stationary sources at the building. EVs can change the financial as well as environmental attractiveness of on-...

background considerable development of mri technology in diagnostic imaging, high cost of mri technology and controversial issues concerning official charges (tariffs) have been the main motivations to define and implement this study. objectives the present study aimed to calculate the unit-cost of mri services using activity-based costing (abc) as a modern cost accounting system and to fairly ...

In this paper, we propose a new discrete-continuous codification of the Chu–Beasley genetic algorithm to address optimal placement and sizing problem distribution static compensators (D-STATCOM) in electrical grids. The discrete part determines nodes where D-STATCOM will be installed. continuous regulates their sizes. objective function considered study is minimization annual operative costs re...

in this article, a finite horizon, multi product and multi period economic order quantity like seasonal items is considered where demand rate is deterministic and known but variable in each period. the order quantities of items come in batch sizes and the end of the period order quantity and, consequently, demand of customers are zero. in addition, storage space is constrained and the problem ...

OBJECTIVES We aimed to estimate the total mean annual treatment cost of different therapy options for patients with moderate-to-severe rheumatoid arthritis (RA) in Greece. METHODS A cost-minimization approach was adopted. An economic model was developed to estimate the direct costs of the three widely used treatments within a 1-year time horizon, from a health care payer perspective, either f...

OBJECTIVE To estimate costs and outcomes of conventional annual Papanicolaou (Pap) test screening compared with biennial Pap test plus speculoscopy (PPS) screening for cervical neoplasms. DESIGN A Markov model compared cost-effectiveness and outcomes of annual Pap tests with biennial PPS. The model includes direct costs of screening, diagnostic testing, and treatment for squamous intraepithei...

The problem of bicriterion scheduling of jobs with identical processing times by uniform processors is considered. The first criterion is the minimization of either total or maximum costs, the second one is the minimization of maximum cost with different cost functions. Polynomial time algorithms are presented to determine all efficient solutions and the optimal solution for a given global crit...

Predicting the maintenance and management costs and replacement age of tractors in agricultural mechanized units, is important from several points. So, doing a timely agricultural operations, more accurate measure of the amount of income  including the cost of these items , determining the useful life of old tractors , replacement age, cost of the process changes and the possibility of examinin...

assembly lines are special kinds of production systems which are of great importance in the industrial production of high quantity commodities. in many practical manufacturing systems, configuration of assembly lines is fixed and designing a new line may be incurred huge amount of costs and thereby it is not desirable for practitioners. when some changes related to market demand occur, it is wo...
