To implement an automatic picking system (APS) in distribution center with high precision and high dynamics, this paper presents a design of a linear induction motor (LIM) drive and robust position controller based on an integral sliding mode control (SMC) scheme. The force disturbance as well as the mechanical parameter variation such as the mass and friction coefficient influences directly on...

We present a performance-optimized algorithm, subsampled open-reference OTU picking, for assigning marker gene (e.g., 16S rRNA) sequences generated on next-generation sequencing platforms to operational taxonomic units (OTUs) for microbial community analysis. This algorithm provides benefits over de novo OTU picking (clustering can be performed largely in parallel, reducing runtime) and closed-...

Due to the use of promotional pricing by supermarkets, there is considerable price variation across weeks within a store and across stores within a week. Consumers may therefore save on their groceries by (1) cherry picking over time (“when”) and (2) cherry picking across stores (“where”). The research focuses on three substantive research questions associated with cherry picking: (1) What vari...

Wigren, M. & Heimann, M. Skin Picking in Prader-Willi Syndrome: A Pilot Study of Clinical Differences and Comorbid Symptoms. Göteborg Psychological Reports, 1999, 29, No. 6. Skin picking constitutes a minor diagnostic criterion for Prader-Willi syndrome and is considered to be a syndrome specific behavior and part of a behavioral phenotype. This study surveyed different aspects and patterns of ...

The effectiveness of a deliberately limited version of Acceptance and Commitment Therapy (ACT) for chronic skin picking was evaluated in a pair of multiple baseline across participants designs. Self-monitoring of skin picking showed that four of the five participants reached near zero levels of picking by post-treatment, but these gains were not fully maintained for three of the four participan...

Aiming at the issues of complex manufacturing processes and unstable bonding after individual in current soft manipulator forming methods, this study investigated mechanical characteristics a pneumatically driven soft-picking formed by stereolithography (SLA) process evaluated its application grasping fruits vegetables. The mainly consists three actuators designed an integrated folded structure...

The medical business of China Post Logistics is developing day by day. China Post Logistics have been using the Parallel partition picking mode for a long time, but too many shortages have appearing in these two years, especially in the order picking cost and efficiency. This paper analyzes the current order picking mode of China Post Logistics and compare with the Parallel partition picking mo...

This paper proposes a universal method, Boost Picking, to train supervised classification models mainly by un-labeled data. Boost Picking only adopts two weak classifiers to estimate and correct the error. It is theoretically proved that Boost Picking could train a supervised model mainly by un-labeled data as effectively as the same model trained by 100% labeled data, only if recalls of the tw...

BACKGROUND AND OBJECTIVES Changes in ESRD reimbursement policy, including proposed bundled payment, have raised concern that dialysis facilities may use "cherry picking" practices to attract a healthier, better insured, or more adherent patient population. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS As part of a national survey to measure beliefs about drivers of quality in dialysis, respon...

BACKGROUND AND AIMS Excoriation (skin-picking) disorder (SPD) is often conceptualized as a behavioral addiction in which aberrant reward processing may play an important role. The current study sought to develop a self-report instrument--the Skin Picking Reward Scale (SPRS)--that measures how strongly skin picking is 'liked' (i.e., the degree of pleasurable feelings while receiving the reward) ...
