Plan de negocio para un espacio de trabajo colaborativo en San Isidro / Business plan for a collaborative workspace at San Isidro

Cueva Davila, Melva Edith, Del Rio Navarro, Marco Antonio, Ferrari Torres, Jose Domingo Augusto, Sedano Pinto, Carla Pamela 05 August 2019 (has links)
El crecimiento estimado para el mercado mundial de espacios de coworking será de 17% para el año 2020, respecto del año anterior (Desmag, 2018), lo cual muestra el dinamismo de esta nueva forma de trabajar a nivel mundial. En el 2013 se registró la primera empresa de coworking en el Perú denominada Comunal, luego ingresaron al mercado otras marcas internacionales y locales. El punto en común entre todas las opciones actuales es que sus modelos de negocios están enfocados en generar comodidad, modernidad y ahorro a sus arrendatarios.  El presente Plan de Negocios tiene como objetivo desarrollar una nueva propuesta de espacios compartidos, denominada Prime Coworking. Este espacio generará ahorro a emprendedores, pequeñas y medianas empresas, siguiendo las tendencias locales e internacionales. Esto se logrará ofreciendo ambientes cómodos, modernos e implementados para la actividad empresarial, y sobre todo que contribuyan a incentivar la retención de sus trabajadores mediante capacitaciones en habilidades blandas. Por último, con la evaluación del proyecto se concluye que el negocio es viable, dado que para una inversión total de 1 007 160 soles se genera un valor actual neto de 338 mil soles. La inversión será financiada con un aporte de los socios de 705 010 soles que generará un valor para el accionista de 311 000 soles, para un periodo de valoración de 5 años y con un payback de 3.6 años. / Coworking spaces global market growth is estimated to be 17% YoY by 2020, (Desmag, 2018), which shows the increasing demand for this new way of working worldwide. In 2013, the first coworking company in Peru called Comunal was registered, then other international and local brands entered the local market. The common point among all market competitors is that their business models are focused on generating comfort, a trendy style and operating savings to their tenants. This Business Plan aims to develop a new proposal for shared spaces, called Prime Coworking, that follows local and international trends and generates savings to entrepreneurs, small and medium enterprises. It does this by offering comfortable, modern and fully implemented environments for doing business and especially by encouraging the engagement of their employees through training in soft skills. Lastly, after our project evaluation it is concluded that the business is profitable, given a total investment of 1 007 160 soles, and an NPV of 338 thousand soles. This investment will be financed with equity of 705 010 soles in shares that will generate a shareholder value of 311 000 soles, for a period of 5 years with a payback of 3.6 years. / Trabajo de investigación

Algebraic Methods for Log-Linear Models

Pribadi, Aaron 31 May 2012 (has links)
Techniques from representation theory (Diaconis, 1988) and algebraic geometry (Drton et al., 2008) have been applied to the statistical analysis of discrete data with log-linear models. With these ideas in mind, we discuss the selection of sparse log-linear models, especially for binary data and data on other structured sample spaces. When a sample space and its symmetry group satisfy certain conditions, we construct a natural spanning set for the space of functions on the sample space which respects the isotypic decomposition; these vectors may be used in algorithms for model selection. The construction is explicitly carried out for the case of binary data.

Representation Theoretical Approach to n-Candidate Voting

Clifford, Grant 01 May 2004 (has links)
Voting theory as been explored mathematically since the 1780’s. Many people have tackled parts of it using various tools, and now we shall look at it through the eyes of a representation theorist. Each vote can be thought of as a permutation of the symmetric group, Sn, and a poll is similar to a linear combination of these elements. Specifically, we will focus on translating and generalizing the works of Donald Saari into more algebraic terms to discover not just one space, but a whole isotypic component essential to positional voting.

Lipschitz and commutator estimates, a unified approach.

Potapov, Denis, denis.potapov@flinders.edu.au January 2007 (has links)
The subject of the thesis is the study of operator functions in the setting of symmetric operator spaces. In this latter setting, it is of great importance to analyze the properties of so-called operator functions A --> f(A), where the variable A is a self-adjoint operator and f is a complex-valued Borel function on the real line. The thesis study the question of differentiability of this type of operator functions. The latter question is intimately related to the study of commutators. Text not only extends existing results to the setting of unbounded self-adjoint linear operators, but it is also shown that this can be obtained via a unified approach utilizing the left regular representation of von Neumann algebras.
