Granularity Helps Explain Seemingly Irrational Features Of Human Decision Making, Joe Lorkowski, Vladik Kreinovich Dec 2014

Granularity Helps Explain Seemingly Irrational Features Of Human Decision Making, Joe Lorkowski, Vladik Kreinovich

Departmental Technical Reports (CS)

Starting from well-known studies by Kahmenan and Tarsky, researchers have found many examples when our decision making -- and our decision making -- seem to be irrational. In this chapter, we show that this seemingly irrational decision making can be explained if we take into account that human abilities to process information are limited; as a result, instead of the exact values of different quantities, we operate with granules that contain these values. On several examples, we show that optimization under such granularity restriction indeed leads to observed human decision making. Thus, granularity helps explain seemingly irrational human decision making.

Steady Quadratic Stokes Flow Past Deformed Sphere: A Novel Perturbation Technique, Deepak K. Srivastava, Nirmal Srivastava, Raja R. Yadav

Applications and Applied Mathematics: An International Journal (AAM)

In this paper, the problem of steady quadratic Stokes flow past a deformed sphere has been tackled with the use of a novel perturbation technique in both situations when a uniform stream is along the axis of symmetry (axial flow) and when it is perpendicular to the axis of symmetry (transverse flow). The most general form of the deformed sphere, governed by polar equation, is considered here for the study. The general expressions for axial and transverse Stokes drag for deformed sphere has been derived up to the second order of deformation parameter for parabolic and stagnation like parabolic flow. …

Study And Manipulation Of Electron Tunneling Through Quantum Dots, Pradeep Krishna Bhadrachalam Dec 2014

Study And Manipulation Of Electron Tunneling Through Quantum Dots, Pradeep Krishna Bhadrachalam

Material Science and Engineering Dissertations - Archive

Fermi-Dirac distribution is the fundamental property which governs the electron energy distribution in solids. At finite temperatures, Fermi-Dirac thermal smearing of electron energies limits the operation of many electronic, opto-electronic and spintronic devices. Examples include single electron transistors, quantum dot resonant tunnel diodes for single photon detection, and single electron turnstile devices. To overcome this intrinsic limitation of Fermi-Dirac thermal smearing, these devices have typically been operated at cryogenic temperatures. Room temperature operation of these devices could be realized, however, if the thermal smearing of electron energies could be suppressed. Until now, studies in the fields of electron-tunneling refrigerators and …

Electrical Engineering Theses - Archive

For the last few decades, Moore's law has been driving the microelectronics industry to achieve high performance with small form-factors at a reasonable cost. The continued miniaturization of the transistors has resulted in unparalleled growth in the electronics industry. Further performance increment via size scaling; however, will not be costeffective and difficult to manufacture. To achieve further performance enhancement at a reasonable cost, advanced packaging is being leveraged. Advanced packaging technologies such as System-on-chip (SOCs), system-in-package (SiPs), and 3-D TSV ICs provide significant power and performance enhancement without having the need to migrate to the higher technology node. As planar …

Hospital Discharge Decision Modeling For Mental Health Inpatients, Peiwen Duan Dec 2014

Hospital Discharge Decision Modeling For Mental Health Inpatients, Peiwen Duan

Industrial Engineering Undergraduate Honors Theses

This research addresses the issue of unnecessary treatment and late discharge for mental health inpatients. In this thesis, a dynamic decision model is proposed to determine the optimal timing to discharge a patient from hospital that considers both the impacts of over-treatment and not enough treatment on patients recovery. We measure the reward of making the discharge decisions in terms of hospitalization cost and readmission cost. The objective is to minimize the total expected cost for patients and provides hospital care providers with theoretical methods to assist them to make a better decision about discharge planning and management.

Multi-Armed Bandits With Applications To Markov Decision Processes And Scheduling Problems, Isa Mithqal Muqattash Dec 2014

Multi-Armed Bandits With Applications To Markov Decision Processes And Scheduling Problems, Isa Mithqal Muqattash

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

The focus of this work is on practical applications of stochastic multi-armed bandits (MABs) in two distinctive settings. First, we develop and present REGA, a novel adaptive sampling-based algorithm for control of finite-horizon Markov decision processes (MDPs) with very large state spaces and small action spaces. We apply a variant of the epsilon-greedy multi-armed bandit algorithm to each stage of the MDP in a recursive manner, thus computing an estimation of the " reward-to-go" value at each stage of the MDP. We provide a finite-time analysis of REGA. In particular, we provide a bound on the probability that the approximation …

Hybrid Technique Of Analysis And Development Of Heat Exchangers For Vuilleumier Heat Pumps, Yogesh Bhalchandra Bedekar

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Vuilleumier heat pumps (VHPs) are heat driven heat pumps working on the Vuilleumier cycle. The Vuilleumier heat pump is a closed system that captures heat at lower temperatures and deposits the captured heat energy to some intermediate temperature at the expense of high temperature heat energy. The heat energy is the input to the system by burning fuel externally. Due to the interfacing between the heat pump and the outside heat sources and heat sinks, heat exchangers represent critical components in the VHP and have a major impact on overall coefficient of performance. High operating pressures, minimal dead volume and …
