Pomona, CA, United States

California State Polytechnic University, Pomona is a public polytechnic university located in Pomona, California, United States. It is one of two polytechnics in the 23-member California State University system and one of only seven in all of the United States. The university is the second largest campus in the CSU, and with an enrollment of 22,156 students, it is the second largest polytechnic university in the United States.The university is designated a National Center of Academic Excellence in Information Assurance Education by the Department of Homeland Security. Cal Poly is one of three CSUs, and one of only five California institutions with this distinction. The university has the oldest and largest Hospitality Management College in all of California, and one of the largest in the US with over 1,000 students. Additionally, Cal Poly has the largest Civil Engineering student population in the nation. It is the only university in Southern California to grant Bachelor's and Master's degrees in agriculture.Cal Poly Pomona currently offers 94 different Bachelor's degrees, 39 Master's degrees, 13 teaching credentials and a doctorate across 9 distinct academic colleges. The university is one among a small group of polytechnic universities in the United States which tend to be primarily devoted to the instruction of technical arts and applied science.Cal Poly Pomona began as the southern branch of the California Polytechnic School in 1938 when a completely equipped school and farm in the city of San Dimas were donated by Charles Voorhis and his son Jerry Voorhis. The satellite campus grew further in 1949 when a horse ranch in the neighboring city of Pomona, which had belonged to Will Keith Kellogg, was acquired from the University of California. Cal Poly Pomona, then known as Cal Poly Kellogg-Voorhis, and Cal Poly San Luis Obispo continued operations under a unified administrative control until they became independent from each other in 1966.Its sports teams are known as the Cal Poly Pomona Broncos and play in the NCAA Division II as part of the California Collegiate Athletic Association . The Broncos sponsor 10 varsity sports and have won 14 NCAA national championships. Wikipedia.

This work focuses on optimal operation of brackish water reverse osmosis (BWRO) plants employing multitrains which have different service times and membrane permeability parameters. A nonlinear optimization problem, based on a previously developed comprehensive RO model that accounts for characteristic curves of booster pumps driving the RO trains and pressure drop along each RO train, is formulated and solved to minimize the overall specific energy consumption (SEC) while maintaining the same overall water production. A 16-17% reduction in SEC is possible by optimizing production allocations among all trains as well as operating conditions within the normal pump operating range in each train. It is shown that optimizing each train individually (without optimizing production allocations) could yield a higher SEC. © 2012 American Chemical Society. Source

Superresolution localization microscopy methods produce nanoscale images via a combination of intermittently active fluorescent probes and algorithms that can precisely determine the positions of these probes from single-molecule or few-molecule images. These algorithms vary widely in their underlying principles, complexity, and accuracy. In this review, we begin by surveying the principles of localization microscopy and describing the fundamental limits to localization precision. We then examine several different families of fluorophore localization algorithms, comparing their complexity, performance, and range of applicability (e.g., whether they require particular types of experimental information, are optimized for specific situations, or are more general). Whereas our focus is on the localization of single isotropic emitters in two dimensions, we also consider oriented dipoles, three-dimensional localization, and algorithms that can handle overlapping images of several nearby fluorophores. Throughout the review, we try to highlight practical advice for users of fluorophore localization algorithms, as well as open questions. Copyright © 2014 by Annual Reviews. Source

A total of 68 species of anomuran and 284 living species of brachyuran crabs are listed as reliably occurring in the Hawaiian Islands. These figures include 12 species of brachyurans known to have been introduced, but not four species of anomurans and nine brachyurans whose identifications are questionable and two species of anomurans and 14 brachyurans that appear to have been recorded from the islands in error. Five species of anomurans and one brachyuran so far only known from the Midway Islands are included in the total number of Hawaiian species, but not five species of brachyurans only known from Johnston Atoll that are included only for their biogeographical interest. The Hawaiian crab fauna shows a predominance of wide ranging Indo-West Pacific species (41% of Anomura, 58% of Brachyura), some degree of endemicity (37% of Anomura, 14% of Brachyura), but it is much impoverished in terms of total number of species when compared with the crab fauna of the Indo-Malayan Archipelago, regarded as a center of diversification for many marine taxa. Several taxonomic changes are also made: Trapezia neglecta Castro, 2003, is ascertained to be a junior synonym of T. intermedia Miers, 1886, and a lectotype and a paralectotype are selected for Grapsus oceanicus Hombron & Jacquinot, 1846 (Grapsidae). © 2011 Magnolia Press.

The previously derived characteristic equation of RO in Li, 2010 [8] is used to describe single- or multi-stage ROs with/without an energy recovery device (ERD). Analysis is made at both the theoretical limit (with analytical solutions provided if possible) and practical conditions (using constrained nonlinear optimization). It is shown that reducing specific energy consumption (SEC) normalized by feed osmotic pressure, or NSEC in ROs can be pursued using one or more of the following three independent methods: (1) increasing a dimensionless group γ=AtotalLpΔΠ0/Qf, (2) increasing number of stages, and (3) using an ERD. When γ increases, the feed rate is adversely affected and the NSEC reduces but flattens out eventually. Using more stages not only reduces NSEC but also improves water recovery. However, The NSEC flattens out when the number of stages increases and ROs with more than five stages are not recommended. Close to the thermodynamic limit where γ is sufficiently large, the NSEC of ROs up to five stages approaches 4, 3.60, 3.45, 3.38 and 3.33 respectively. The ERD can significantly reduce the NSEC, theoretically to 1, while the corresponding recovery approaches zero. The NSEC becomes larger when the required water recovery increases. It is found that a combination of all three methods can significantly reduce the NSEC while maintaining a high recovery and a reasonable feed or permeate rate. An NSEC around 2.5-2.8 with an 80% water recovery may be possible using 3-5 RO stages and an ERD of 90% efficiency operated at a γ about 3-5 (or Qf=0.2-0.3 AtotalLpΔΠ0). © 2011 Elsevier B.V. Source

Abstract This paper models a closed-loop supply chain (CLSC) with a manufacturer and its supply channels - recycle channel and reliable supply channel. We assume that the manufacturer may reuse the recycled main product component and remanufacture the product. The recycle channel shows stochastic recovery rate. Both the centralized (integrated) recycle channel CLSC and the decentralized recycle channel CLSC are studied. The optimal production decision and the optimal acquisition pricing decision are obtained for both the deterministic demand and the stochastic demand cases. Further, the paper discusses the supply chain inefficiency in this CLSC. It is shown that under decentralized recycle channel structure, the optimal acquisition price is always lower than the optimal acquisition price under centralized recycle channel structure, causing reduced recycle quantity and lower remanufactured quantity, which is similar to the effect of double marginalization in the normal forward supply chain. The cost difference between the two supply channels also increases such double marginalization impact. In order to reduce such supply chain inefficiency, two contracts (complete compensation and partial compensation) are proposed. It is shown that under certain conditions, both contracts are Pareto improving for the decentralized supply chain and can be used to coordinate the CLSC. Numerical examples are used to illustrate the results. The numerical examples show the different preferences of supply chain parties on different risk reductions in the decentralized system. In general, the interests on demand risk reduction is aligned between the recycle channel supplier and the manufacturer with the manufacturer showing higher motivation; on the other hand, recycle channel supplier and the manufacturer may have conflict of interests in supply risk reduction when the supply risk is low, and their interests are aligned when the supply risk is high. © 2015 Elsevier B.V.
