Estudio de factibilidad de distribución de boxes con insumos para cocinar / Feasibility study of distribution of boxes with supplies for cooking

Guzman Pariona, Ram Isaias, Martinez Suarez, Franco Alonso, Ordaya Villanueva, Katherine Eliana, Su Fung, Fernando, Trigoso Tàvara, Frank Lenin 29 June 2019 (has links)
El ritmo de vida de las personas en la actualidad se ha acelerado a tal punto que no cuentan con el tiempo necesario para realizar actividades esenciales. Destacando principalmente la función de cocinar, la cual resulta extenuante debido al engorroso proceso que implica llevarla a cabo. El proceso comprende el traslado al lugar de compra, la búsqueda de los insumos, la selección de los insumos, las largas colas para pagar, el lavado de los insumos así como el picado de los mismos, entre otras. Por ende, se propone una solución alternativa a este problema, la cual consiste en el delivery a través de la venta online de boxes con insumos frescos sin cocinar picados y en las cantidades exactas de diversos platillos criollos. / The rhythm of life of the persons at present has hastened to such a point that they do not count with the necessary time to realize essential activities. Emphasizing principally the function to cook, which turns out to be exhausting due to the bothersome process that implies carrying out it. The process comprises the transfer to the place of buy, the search of the inputs, the selection of the inputs, the long tails to pay, the wash of the inputs as well as stung of the same ones, between others. Therefore, an alternative solution to this problem is proposed, which consists of the delivery through the online sale of boxes with fresh uncooked inputs chopped and the exact quantities of various Creole dishes. This paper seeks to determine the financial viability of the project in question in order to validate the possibility of implementing it in a real-world scenario. / Trabajo de investigación

Investigation into load bridging effect for block class pallets as a function of package size and pallet stiffness

Morrissette, Steven Michael 08 July 2019 (has links)
Pallets and corrugated boxes are ubiquitous in the global supply chain. However, the interactions that exist between the boxes and pallet are ignored during the pallet design process resulting in an over design of pallet performance and the waste of raw materials. The goal of this research is to understand how pallet performance is affected by headspace, box size, and base design across multiple support conditions using block class wooden pallets. Headspace and base design had no effect on pallet deflection for the experimental weights used throughout testing. The effect of box size was significant on pallet deflection across multiple support conditions. The effect was greatest for lower stiffness pallets and low stiffness support conditions (RAW) with up to a 50% reduction in pallet deflection observed by switching from small to large boxes on a very low stiffness pallet. Evaluation of pressure mat data showed an increase in the redistribution of pressure away from the center of the pallet and towards the supports as box size increased. The redistribution of pressure towards the supports is known as load bridging and validates the observed reduction in pallet deflection as a function of box size. The results indicate that incorporating the effect of packages into current pallet design practices could result more effective and cheaper pallet designs. / Master of Science / Transportation and storage of material goods at a national and international level is an integral part of our economy with pallets and corrugated boxes making up the majority of packaging materials. Currently, the interactions that exist between the boxes and pallet are ignored during pallet design resulting in an over design of pallet performance and a waste of raw materials. Understanding the interactions that exist in a unit load is important in optimizing pallet performance, reducing the amount of raw materials used, and ultimately reducing cost. This research project is specifically focused on the interactions between corrugated boxes and block class wooden pallets. The effect of headspace (the gap between the products and the top of the box) and box size was investigated as a function of pallet stiffness, support condition, and bottom deck design. Both pallet deflection and the pressure distribution on the top surface of the pallet were examined to evaluate pallet performance. It was found that headspace does not have an effect on pallet deflection unless the weight of the unit load exceeds 3,500 lbs. for small boxes and 1,750 lbs. for large boxes. Base design showed no significant effect on pallet deflection for all of the support conditions evaluated. The effect of box size had a major effect on the deflection of the pallet. Large boxes showed the greatest change especially when lower stiffness pallets were used. Increasing the box size can reduce the deflection of the pallet as much as 50% which means that pallets supporting larger boxes could support much more weight than currently estimated. Evaluation of pressure mat data showed that when the size of the boxes increased, more pressure is distributed towards the supports. More pressure is applied to the pallet section on the top of the supports; therefore, less pressure is available to cause pallet bending. This finding validates the observed reduction in pallet deflection as a function of box size. The obtained results help pallet designers to incorporate the interactions between the packages and the pallet into their design process which will allow them to reduce the amount material used for pallet.

Γραμμική - διαφορική κρυπτανάλυση και κατασκευή κρυπτογραφικά ασφαλών S-boxes / Linear - differential cryptanalysis and secure S-boxes construction

Γιαννακόπουλος, Χαράλαμπος 23 November 2007 (has links)
Σε αυτή τη Μεταπτυχιακή Διπλωματική Εργασία γίνεται μία προσπάθεια κατασκευής ασφαλέστερων block ciphers (Κεφ.1). Αρχικώς παρουσιάζουμε αναλυτικά το θεωρητικό υπόβαθρο της Γραμμικής Κρυπτανάλυσης (Κεφ.2) και της Διαφορικής Κρυπτανάλυσης (Κεφ.3). Στη συνέχεια, προχωρούμε σε μια εφαρμογή της Γραμμικής και Διαφορικής Κρυπτανάλυσης στον αλγόριθμο CAST-128 (Κεφ.4), που είναι ένας σύγχρονος block cipher αλγόριθμος. Στο Κεφ.5 αναφερόμαστε στις σχεδιαστικές παραμέτρους ενός block cipher (S-box Design, Framework Κρυπτογραφήματος, Key Schedule και Round Function). Η συμβολή μας συνίσταται στην κατασκευή κρυπτογραφικά ασφαλών S-boxes με τη χρήση Bent συναρτήσεων και συναρτήσεων Maiorana και η μελέτη της μη γραμμικότητας του προκύπτοντος κρυπτοσυστήματος (Κεφ.6). Στο τελευταίο κεφάλαιο (Κεφ.7) αναφερόμαστε στις μελλοντικές προεκτάσεις και στο ερευνητικό πλάνο που έχουμε θέσει με αφετηρία αυτή τη Μεταπτυχιακή Διπλωματική Εργασία. Στο Παράρτημα Α παραθέτουμε τον Κώδικα Υλοποίησης της κατασκευής των S-boxes. / In this Master Thesis we make an attempt to construct secure block ciphers (Chap.1). First of all, we present in details the theoretical background of Linear Cryptanalysis (Chap.2) and Differential Cryptanalysis (Chap.3). Then we apply Linear and Differential Cryptanalysis in CAST-128 algorithm (Chap.4), which is a modern block cipher algorithm. In Chap.5 we present the design parameters of a block cipher (S-box Design, Feistel Framework, Key Schedule and Round Function). Our contribution is the construction of cryptographically secure S-boxes using Bent Functions and Maiorana Functions and also we study the non-linearity of the constructed cryptosystem (Chap.6). In the last Chapter (Chap.7) we present our future research plan, based on this Master Thesis. The Source Code of the S-boxes construction can be found in Appendix A.
