About twin primes and distribution of primes
No full textThis paper give us a demonstration of twin primes conjecture using approximation of function �(iupsilon) that we introduce in section 6. Section 1-5 give us introduction to terminology and a clarification on (iupsilon) terms. In particular section
5 is really important because of its Lemma. Section 7 reassume foregoing explanations and it give us two theorems and one corollary;the theorem 7.2 give us exact approximation of twin primes counting function
A reliability-based methodology for resilient spare parts planning and control
No full textGeo-political conflicts, financial crises, natural disasters, pandemics, human operational errors, and other disruptive events can affect supply chain integrity with unpredictable consequences. In addition, intermittent demand patterns and strict service requirements enhance the complexity of Spare Parts Supply Chains (SPSCs). SPSC resilience has become a significant challenge in today’s increasingly competitive business environment.
This study presents a reliability-based methodology with a customer-oriented perspective to support industrial companies in spare parts planning and control. This original approach provides resilience to SPSCs by defining a statistical variable to study supply chain variabilities and externalities, aiding stockout risk control, and suggesting spare parts management plans. The application of the proposed methodology in a case study of a packaging machine company is illustrated
Location-allocation problem in a multi-terminal cross-dock distribution network for palletized perishables delivery
No full textA multi-terminal cross-dock distribution network deals with widespread suppliers through intermediate logistic actors that collect products from supplier facilities and use cross-docking hubs for consolidation and distribution. In these hubs, incoming products are unloaded, sorted, and consolidated with others into new shipments heading towards retailers and final customers. This type of network is suitable for the express delivery of fast-moving products, such as perishables, guaranteeing shipment within a short time window (e.g., one day). The strategic design of a multi-terminal cross-dock network deals with solving the location-allocation problem (LAP) because hub location and flow allocation play a pivotal role in reducing transportation time and cost.
This paper proposes a mixed-integer linear programming (MILP) model that solves the strategic problem of a multi-terminal cross-dock network design for perishables in an augmented LAP formulation. The aim is to exploit the potential hub location and handling capacity (i.e., location problem), as well as the optimal destination hub for unloading/loading operations (i.e., allocation problem) per truck, while minimizing the total logistics costs and increasing truck utilization.
The proposed model is applied to a cross-dock multi-terminal network owned by an Italian company specializing in the fast delivery of palletized perishable products. A comparative what-if multi-scenario analysis illustrates the change in the traveling cost and truck utilization according to several factors, such as the opportunity to open (close) new (existing) hubs in Italy
Established and Outsiders at the Same Time - Self-Images and We-Images of Palestinians in the West Bank and in Israel
No full textPalestinians frequently present a harmonizing and homogenizing we-image of their own national we-group, as a way of counteracting Israeli attempts to sow divisions among them, whether through Israeli politics or through the dominant public discourse in Israel. However, a closer look reveals the fragility of this homogenizing we-image which masks a variety of internal tensions and conflicts. By applying methods and concepts from biographical research and figurational sociology, the articles in this volume offer an analysis of the Middle East conflict that goes beyond the polar opposition between “Israelis” and “Palestinians”. On the basis of case studies from five urban regions in Palestine and Israel (Bethlehem, Ramallah, East Jerusalem, Haifa and Jaffa), the authors explore the importance of belonging, collective self-images and different forms of social differentiation within Palestinian communities. For each region this is bound up with an analysis of the relevant social and socio-political contexts, and family and life histories. The analysis of (locally) different figurations means focusing on the perspective of Palestinians as members of different religious, socio-economic, political or generational groupings and local group constellations – for instance between Christians and Muslims or between long-time residents and refugees. The following scholars have contributed to this volume: Ahmed Albaba, Johannes Becker, Hendrik Hinrichsen, Gabriele Rosenthal, Nicole Witte, Arne Worm and Rixta Wundrak. Gabriele Rosenthal is a sociologist and professor of Qualitative Methodology at the Center of Methods in Social Sciences, University of Göttingen. Her major research focus is the intergenerational impact of collective and familial history on biographical structures and actional patterns of individuals and family systems. Her current research deals with ethnicity, ethno-political conflicts and the social construction of borders. She is the author and editor of numerous books, including The Holocaust in Three Generations (2009), Interpretative Sozialforschung (2011) and, together with Artur Bogner, Ethnicity, Belonging and Biography (2009)

The Last Bastion of Architecture
No full textThe essay is a critical interpretation of Rem Koolhaas' theory of Bigness. In fact, of the theories that have best marked the development of architectural culture since World War II – from those of the Smithsons to Rossi, from Eisenman to Venturi and Scott Brown – Rem Koolhaas’s theory of Bigness has probably, more than any other, investigated the intrinsic possibilities of architecture at the end of the 20th century. In light of the number of pseudotheories that have largely characterized the last decade, Bigness is the last constituent fact of recent history: an extremely lucid attempt to draw to a conclusion a history that goes back to the very invention of the modern city, comparing it with architecture’s own immutable core, its physicality, even exposing the theory of Bigness itself to the risk of total failure. The essay investigates the development of the theory of Bigness from its incubation in Koolhaas’s book Delirious New York in 1978, to the "official" presentation in S,M,L,XL in december 1995. The essay presents some parts of the PhD research "L'architettura dei libri. Progetto, scrittura, editoria nella ricerca architettonica contemporanea", developed by the author at Università degli studi G. D'Annunzio, Chieti, Facoltà di Architettura di Pescara, in 2001-2004.
