BUDGET RATCHETING IN GOVERNMENTAL BUDGETING: AN EMPIRICAL INVESTIGATION

open access: yesJurnal Tata Kelola dan Akuntabilitas Keuangan Negara, 2020
Previous literature has documented various aspects of behavior in the budgeting process. Behavioral problems that are often discussed include budgetary slack and opportunistic behavior that occur due to information asymmetry.

Compressive fatigue behavior of graded tantalum scaffolds produced by electron beam powder bed fusion

open access: yesJournal of Materials Research and Technology, 2023
In this study, graded tantalum scaffolds were manufactured by electron beam powder bed fusion (EB-PBF). Compression-compression fatigue testing was conducted on the EB-PBF built graded tantalum scaffolds.

Study of Cyclic Plasticity and Creep Ratchet Behavior of PTFE

open access: yesApplied Sciences, 2023
Due to its superior corrosion resistance and low coefficient of friction, polytetrafluoroethylene (PTFE) is extensively used in the aerospace, machinery, chemical, and pharmaceutical industries. However, PTFE components encounter complex alternating stresses, resulting in ratchet and creep, which will affect the component’s reliability. It is therefore

Mechanical behavior of large-diameter pipe elbows under low-cyclic loading

open access: yesJournal of Sustainable Construction Materials and Technologies, 2023
Large-diameter steel pipes are often used for transmitting and distributing water, gas, and oil products from the source to the end user. These pipelines are mainly oriented by using pipe el- bows due to their high flexibility along their routes.

Viscoplastic Constitutive Equations for Ratchetting Behavior

open access: yesTransactions of Materials Processing, 2005
Inelastic deformation behavior of metals and alloys is considered rate dependent. Uniaxial ratcheting experiments performed by Ruggles and Krempl, and Hassan and Kyriakides exhibited that higher mean stress for a fixed stress amplitude resulted in higher ratchet strain within a rate independent framework and higher stress rate resulted in lower ratchet

Local Search and the Evolution of World Models

open access: yesTopics in Cognitive Science, EarlyView., 2023
Abstract An open question regarding how people develop their models of the world is how new candidates are generated for consideration out of infinitely many possibilities. We discuss the role that evolutionary mechanisms play in this process. Specifically, we argue that when it comes to developing a global world model, innovation is necessarily ...
