Impact of product-design strategies on the operations of a closed-loop supply chain

Abstract: This study investigates product design and its impact on the operations of a two-echelon closed-loop supply chain (CLSC). Research findings reveal that remanufacturing does not necessarily enhance the profitability of the supplier or the manufacturer, but adjusting product-design strategies helps to curb loss if profitability suffers. An environmental impact analysis identifies an interval for the base unit remanufacturing cost, within which remanufacturing is beneficial. We then obtain the condition under which the environmental impact can be mitigated by product design. These results shed insights for supply chain managers in their operational decisions and policy-makers in properly regulating remanufacturing activities.

Reading the Geochemical Fingerprints of Archean Hot Subduction Volcanic Rocks: Evidence for Accretion and Crustal Recycling in a Mobile Tectonic Regime

Abstract: In certain Cenozoic arcs, rare exotic volcanic rocks occur with "normal" tholeiitic to calc-alkaline lavas. These include boninites, arc picrites, adakites, high-magnesian andesites (HMA), and Nb-enriched basalts (NEB). They are associated with convergent margins characterized by high heat flow, stemming from subduction of hot young oceanic lithosphere, ridge subduction, or slab windows. We term these "hot subduction volcanic rocks". Boninites and picrites are melts of variably depleted mantle wedge induced by slab dehydration, whereas adakites reflect slab melt and mantle wedge interaction. HMA form by hybridization of adakitic melts with the mantle wedge and NEB by melting of the residue of HMA hybridization. Given the constrained geodynamic setting in which these rare volcanic rock types form, their presence in Archean greenstone belts bears on the competing models of plate tectonic subduction-accretion-recycling versus "statist" autochthonous-parautochthonous models. Boninites have recently been documented from the following areas: 3.8 Ga Isua; 3.0 Ga Mallina, Pilbara; 2.7-2.8 Ga belts in Superior Province and Dharwar Craton; and 2.8 Ga Karelian (Baltic Shield). Picrites having arc characteristics are known from the 3.8 Ga Isua, 3.0 Ivisaartoq, 2.7 Ga Wawa, and 2.55 Ga Zunhua belts, China. Structurally, many Paleoarchean to Neoarchean greenstone belts are comparable to Phanerozoic accretionary orogens, such as the Altaids and Cordilleran orogens (e.g., southern Alaska, Wrangellia). Collectively, these observations are consistent with a mobilist geodynamic regime for most Archean greenstone terranes.

Information Fusion and Semi-Supervised Deep Learning Scheme for Diagnosing Gear Faults in Induction Machine Systems

Abstract: There has been an increasing interest in the design of intelligent diagnostic systems for industrial applications. The key requirement in the design of practical diagnostic systems is the ability for decision making in high-dimensional feature spaces, where the prior knowledge about the system states in terms of labels is very limited. Moreover, the problem of diagnosing simultaneous defects is rarely addressed on real industrial applications. This paper aims to develop a semi-supervised deep-learning scheme for diagnosing multiple defects including simultaneous ones in a gearbox directly connected to an induction machine shaft. This scheme consists of two main modules: information fusion and decision making. The former integrates captured multiple sensory streams into a very high dimensional feature space. The latter uses a semi-supervised deep learning procedure to minimize the human interaction during the training and maximize the diagnostic efficiency. This scheme facilitates learning and diagnosing defects under harshest conditions 1) where only a few number of labeled samples are collected together with a large number of unlabeled samples, and 2) in a very high-dimensional feature space. Several state-of-the-art semi-supervised and supervised learners have also been included in the scheme, enabling a comparative experiment for diagnosing simultaneous defects.

Psychological Adjustment, Coping, and Emotion Regulation as Predictors of Posttraumatic Growth

Abstract: The present study examined factors contributing to reported benefits of traumatic experiences or posttraumatic growth (PTG) in a college sample. Specifically, we examined dimensions typically associated with trauma recovery (i.e., psychological functioning, coping, emotion regulation) and features of the trauma (i.e., number and recency of traumatic events, average, and maximal distress). Participants (N= 193) completed standardized questionnaires measuring these constructs. Results indicated that active coping and subjective well-being independently contributed to PTG, but social desirability and symptom distress were independent of growth. These results were consistent with study expectations. Although not specifically predicted, maximal trauma distress also uniquely predicted PTG. Contrary to expectations, effective emotion regulation did not contribute to PTG.
