Bikeshare provides important first mile–last mile, commuting, circulation, and sightseeing options in many cities. can also be healthy convenient for users. Throughout the year, holidays occur that change typical bikeshare activity patterns. Existing literature shows mixed results relating to ridership impacts of holidays: some research these days may result higher ridership, whereas others sho...

Abstract Heuristic rules are appropriate, if a decision maker wants to set the price of new product or product, whose past variation is low, and budget limitations prevent use marketing experiments customer surveys. Whereas such not guaranteed provide optimal price, generated profits should be as close possible their values. We investigate eleven pricing that do require knows response function ...

Population growth and climate change require efficient use of water resources per unit area. In this study, the relationships between irrigation systems, land sizes crop patterns farmers in coastal areas were determined to provide useful information for better agricultural management. A survey study was conducted with 170 using stratified sampling method. The relationship varieties, methods by ...

امروزه توسعه سیستم‌های کارآمد و اثربخش بهداشت درمان به یکی از نگرانی‌های اصلی دولت‌ها تصمیم‌گیرندگان تبدیل شده است. تأمین به‌موقع دارو کارایی سیستم موجودی توزیع، نقشی حیاتی در زنجیره بیمارستانی دارند برای افزایش این فعالیت‌ها، فرآیند تصمیم‌گیری مناسب مدیریت ضروری نظر می‌رسد. پژوهش یک مدل دوهدفه به‌صورت برنامه‌ریزی خطی عدد صحیح مختلط جریان اطلاعات ارائه اهداف حداقل­کردن هزینه‌های خرید، نگهداری، ...

نخستین گام در راستای تحلیل و ارزیابی ریسک‌های زنجیره تأمین شناسایی این ریسک‌ها است. روش‌های مرسوم بر اساس فیلترهای دستی یا خودکار داده‌­محور ارائه شده فیلتر به‌­دلیل محدودیت‌های نمونه‌گیری دارای مشکلات اعتبارسنجی هستند از طرف دیگر مبتنی داده، داده‌های ریسک که پیچیده مبهم هستند، عملکرد ضعیفی دارند. برای پرکرده خلل پژوهشی، پژوهش، چارچوبی تعاملی بین تحلیل‌­گر ماشین حجم وسیعی حوزه مواد غذایی با است...

In regression analysis of count data, independent variables are often modeled by their linear effects under the assumption of log-linearity. In reality, the validity of such an assumption is rarely tested, and its use is at times unjustifiable. A lack-of-fit test is proposed for the adequacy of a postulated functional form of an independent variable within the framework of semiparametric Poisso...

DNA microarray provides a powerful basis for analysis of gene expression. Data mining methods such as clustering have been widely applied to microarray data to link genes that show similar expression patterns. However, this approach usually fails to unveil gene-gene interactions in the same cluster. Association rule mining and loglinear models have been used for this purpose, but their inherent...

Linear Discriminant Analysis (LDA) has been established as an important means for dimension reduction and decorrelation in speech recognition. The major points of criticism of LDA are that it uses an ad hoc and non-discriminative training criterion, and that the estimation is performed in a separate preprocessing step. This paper presents a new discriminative training method for the estimation ...

Experimental solubilities of four antiepileptic drugs, that is, lamotrigine, diazepam, clonazepam, and phenobarbital in propylene glycol + water mixtures at 298.15 K were reported. The solubility of drugs was increased with the addition of propylene glycol, and the maximum values are observed in neat propylene glycol. The Jouyban-Acree model was used to fit the experimental data, and the solubi...

String-to-string transduction is a central problem in computational linguistics and natural language processing. It occurs in tasks as diverse as name transliteration, spelling correction, pronunciation modeling and inflectional morphology. We present a conditional loglinear model for string-to-string transduction, which employs overlapping features over latent alignment sequences, and which le...
