Premium e-grocery: exploring value in logistics integrated service solutions
(12.02.2009)E-grocery is gradually becoming viable or a necessity for many families. Yet, most e-supermarketsare seen as providers of low value “staple” and bulky goods mainly. While each store has a large number of SKU available, ... -
Preparation and characterization of freely-suspended graphene nanomechanical membrane devices with quantum dots for point-of-care applications
(MDPI, 2020-01-01)We demonstrate freely suspended graphene-based nanomechanical membranes (NMMs) as acoustic sensors in the audible frequency range. Simple and low-cost procedures are used to fabricate NMMs with various thicknesses based ... -
Preparation of molecularly imprinted metoprolol sensor from poly(aniline-co-p-toluene sulfonic acid)
(Center of Excellence in Electrochemistry, 2022)In this study, the metoprolol (MTP), which is a beta-blocker class molecule used in hypertension treatment, was determined by modifying the glassy carbon electrode (GCE) with a molecular imprinting technique. Firstly, ... -
Preschool children’s self-regulation and learning behaviors: The moderating role of teacher–child relationship
(Springer, 2022-02)Background Children's approach to learning is essential for both academic achievement and socio-emotional well-being. This competence is influenced by both individual (self-regulation) and environmental factors (teacher-child ... -
Preschool children’s social competence: the roles of parent–child, parent–parent, and teacher–child relationships
(Taylor & Francis, 2021-11-02)Children's relationships with adults (e.g. parents and teachers) and within-family relationships (e.g. parent-parent) are important drivers for the development of children's social competence. The current study examined ... -
Pressure drop and heat transfer characteristics of nanofluids in horizontal microtubes under thermally developing flow conditions
(Elsevier, 2015-10)This study presents pressure drop and heat transfer characteristics of water based nanofluids with TiO2 and Al2O3 nanoparticles of various mass fractions in horizontal smooth hypodermic microtubes with an outer diameter ... -
Prevalence of depression, anxiety, stress, and anger in Turkish prisoners
(Wiley, 2013-09)In Turkey, prison studies are rare and the mental health status of prisoners has not received proper attention. The purpose of this cross-sectional and descriptive study was to assess the prevalence of depression, anxiety, ... -
Preview control-based jumping and spot-jogging trajectory generation for quadruped robots
(IEEE, 2023)This work presents a vertical center of mass (CoM) trajectory generation approach based on preview control for quadruped robots to accomplish agile locomotion tasks such as jumping and jogging. Conventionally, preview ... -
Price and quality decisions of a service provider under heterogeneous demand
(Boğaziçi Üniversitesi, 2019)A monopolist service provider's quality and price decisions are analyzed in a vertically differentiated market where customers demand different quantities of a service. We find that depending on the relative sizes of the ... -
Price estimation by random walk mean reversion in day-ahead electricity market
(IEEE, 2019)The fluctuations in the Day-ahead electricity market (DAM) prices generally follow the periodic demand variance. However, the observations of historical data also reveal large jumps or spikes that might be defined as the ... -
Price of regulations: Regulatory costs and the cross-section of stock returns
(Oxford University Press, 2024-01)Regulations introduce significant fixed costs and add to operating leverage. Fixed regulatory costs that contribute to operating leverage should generate a risk premium. To explore whether such a premium exists, we introduce ... -
Pricing decisions in a strategic single retailer/dual suppliers setting under order size constraints
(Informa Group, 2016)In this paper, we study a duopolistic market of suppliers competing for the business of a retailer. The retailer sets the order cycle and quantities from each supplier to minimize its annual costs. Different from other ... -
Pricing for open access femtocell networks using market equilibrium and non-cooperative game
(IEEE, 2012)In this paper, we address the pricing problem in open-access femtocell networks. We use economic and game theoretic approaches such as market equilibrium and non-cooperative game to propose novel pricing schemes. In our ... -
Pricing of national brands versus store brands: market power components, findings and research opportunities
(Edward Elgar Publishing, 2009)Among the most important activities for supermarket retailers is the creation and marketing of store brands, also known as private label brands. Given the increasing quality-equivalence between national brands and store ... -

Prioritization and parallel execution of test cases for certification testing
(2021-06-08)Systems that are developed in the consumer electronics domain are subject to testing for certification regularly. For instance, each Smart TV product must go through a certification process that is regulated by application ... -
Prioritization and parallel execution of test cases for certification testing of embedded systems
(Springer, 2022-07-22)Testing for certification of embedded systems is common in consumer electronics domain. Application vendors provide test suites that have to be repeatedly executed for each product. Multiple test stations can be used in ... -
Prioritization of test cases with varying test costs and fault severities for certification testing
(IEEE, 2020-10)We present an industrial case study on the application of test case prioritization techniques in the context of certification testing in consumer electronics domain. Test execution times and fault severities are subject ... -
A prism-based non-linear optical readout method for MEMS cantilever arrays
(Elsevier, 2016-10-15)This paper demonstrates the use of a single right-angle prism for the optical readout of micro-electro-mechanical systems (MEMS) cantilever arrays. The non-linear reflectivity arisen from the internal reflection at the ... -
Privacy enforcement through policy extension
(IEEE, 2016)Successful coalition operations require contributions from the coalition partners which might have hidden goals and desiderata in addition to the shared coalition goals. Therefore, there is an inevitable risk-utility ...
