A new extended formulation with valid inequalities for the Capacitated Concentrator Location Problem
No full textWe present a new disaggregated formulation of the Capacitated Concentrator Location Problem (CCLP) using the notion of cardinality of terminals assigned to a concentrator. This formulation consists of O(mnn) variables and constraints, where m denotes the number of concentrators and n the number of terminals, respectively. We prove that this extended formulation is stronger than the traditional one. We also present two classes of inequalities exploiting the cardinality effect of the extended formulation. The first class is a generalization of the well-known Cover and (1, k)-Configuration inequalities, which collectively are stronger than the original Cover and (1, k)-Configuration inequalities. The second class, called the 2-Facility Cardinality Matching Inequality, holds for the uncapacitated version of the Concentrator Location Problem and can be lifted to become a strong inequality for CCLP. We solve the LP relaxation of the extended formulation and use separation heuristics to identify and sequentially add the previous valid inequalities to improve the lower bound. This approach is embedded in a branch-and-bound and results in a branch-and-cut approach. We test our solution approach on a large set of benchmark problems. The experimentation shows that we can identify the optimal solution at the root node in most of the problem instances with up to 50 concentrators and 50 terminals. For larger sized test problems with up to 100 concentrators and 1000 terminals, the branch-and-cut procedure using the disaggregated formulation outperforms the branch-and-cut procedure applied to the traditional formulation both in terms of CPU and the required number of branch-and-bound nodes

Notules sur Emptiness: A Double Comic Strip de Bharath Murthy
No full textÀ travers ces 12 notules je cherche à montrer comment l’auteur Bharath Murthy a su développer une BD « scientifique » ici plus concrètement philosophique sur le la présence-absence d’une essence appelée « âme » (ou « moi », « soi », « dieu », etc.) dans la tradition occidentale et réaffirmée jusque dans l’IA par certains, et déconstruite par l’« emptiness » aporétique bouddhique en utilisant les techniques spécifiques de la bande dessinée procurées par le texte et l’image (du bleed à la graphiation).Through these 12 “footnotes” I try to show how the author Bharath Murthy has been able to develop a "scientific" comic strip, here more concretely a philosophical one, on the presence-absence of an essence called "soul" (or "self", "self", "god", etc.) in the Western tradition and reaffirmed in AI by some, and deconstructed by the Buddhist aporetic "emptiness", using the specific techniques of comics provided by the text and the image (from bleed to graphiation)

Shared autonomous vehicle system designs for major metro areas : an examination of geofencing, ride-sharing, stop-location, and drivetrain decisions
No full textWith autonomous vehicles (AVs) in the testing phase, researchers and planners must resort to simulation techniques to explore possible futures regarding shared and automated mobility. An agent-based discrete-event transport simulator, POLARIS, is used throughout this dissertation to simulate passenger and freight travel in regions with a shared AV (SAV) mobility option. Using this framework, three broad areas of SAV design are explored – geographical restrictions via geofences, operational modifications via pickup-dropoff (PUDO) stops, and the use of all-electric drivetrains – using the case studies of Bloomington and Chicago in Illinois.
Constraining SAVs within pre-defined geofences indicate that empty vehicle-miles-traveled (eVMT) can be curtailed when service areas in Chicago have a balanced mix of trip generators and attractors. Geofences also help lower spatial response times, system-wide VMT across all modes, and ensure uniform access to SAVs. Dynamic ride-sharing (DRS) is useful in lowering VMT and percent eVMT that arises from sprawling when demand is low, whereas savings from DRS is highest when all demand within smaller regions are served by SAVs. Various PUDO spacings and trip-demand densities with fixed mode shares in Bloomington reveal that greater PUDO spacing or distances between stops and higher levels of SAV use or trip demand increases AVO by up to 11% per 4-seater SAV, on average. Aggregation also decreases SAV VMT (by up to 20%) compared to door-to-door SAV fleet operations without DRS or PUDOs. Higher SAV mode shares in a forecasted scenario for Chicago outline total VMT savings of about 2 to 3%, even though SAV VMT increases from serving more trips. A quarter-mile PUDO spacing is recommended in downtown regions to keep walking trips short, but further analysis on congestion spillback is warranted.
A variety of electric SAV (SAEV) fleet designs and charging strategies show that a mixed fleet of short (100-mi) and long (250-mi) range SAEVs performs better than a homogenous short-range fleet, with lower empty vehicle miles traveled (eVMT) and lower idling time. Charging and service priority policies are both required, but at different times of the day to accommodate slow Level 2 chargers, but is not as important for DCFC charging stations. SAEVs can stay in place longer (1 hr versus 15 min) to keep eVMT low, but only if long-range SAEVs are in the fleet and the region is small. SAEVs in large regions like Chicago are exposed to location-specific trip requests when idling in place, and need to have high average state of charge (SoC) across the fleet to serve all incoming requests. Smart siting of EVCS and availability of fast chargers remain key to minimizing fleet size and keeping response times low.Civil, Architectural, and Environmental Engineerin
Magnetic anomalies of offshore Krishna-Godavari basin, eastern continental margin of India
No full textThe marine magnetic data acquired from offshore Krishna-Godavari (K-G) basin, eastern continental margin of India (ECMI), brought out a prominent NE-SW trending feature, which could be explained by a buried structural high formed by volcanic activity. The magnetic anomaly feature is also associated with a distinct negative gravity anomaly similar to the one associated with 85°E Ridge. The gravity low could be attributed to a flexure at the Moho boundary, which could in turn be filled with the volcanic material. Inversion of the magnetic and gravity anomalies was also carried out to establish the similarity of anomalies of the two geological features (structural high on the margin and the 85°E Ridge) and their interpretations. In both cases, the magnetic anomalies were caused dominantly by the magnetization contrast between the volcanic material and the surrounding oceanic crust, whereas the low gravity anomalies are by the flexures of the order of 3-4 km at Moho boundary beneath them. The analysis suggests that both structural high present in offshore Krishna-Godavari basin and the 85°E Ridge have been emplaced on relatively older oceanic crust by a common volcanic process, but at discrete times, and that several of the gravity lows in the Bay of Bengal can be attributed to flexures on the Moho, each created due to the load of volcanic material
Effect of Grain Size on the Microwave Dielectric Characteristics of High-Energy Ball-Milled Zinc Magnesium Titanate Ceramics
No full textUsing solid-state reaction route and high-energy ball milling technique Zn1−xMgxTiO3 (x = 0–0.5) compositions were synthesized. These ball milled samples were sintered at 1100°C for 2 h and microwave dielectric properties such as dielectric constant (ε’), quality factor (Q) and temperature coefficient of resonant frequency (τf) were studied. Significant improvement in quality factor of ∼ 65% was observed for x = 0.3. To understand the effect of sintering duration on the microwave dielectric properties, single phase Zn0.7Mg0.3TiO3 samples were sintered at 1100°C for different durations from 2 to 20 h. The grain size increases with sintering duration and it influences to enhance the microwave dielectric properties and as a result, the quality factor further improved by three times. The dielectric constant and temperature coefficient of resonant frequency showed a slight improvement of ∼ 10%–15% with sintering duration
