Design and Implementation of Multi-head Presentation Software for the iOS Platform
ShareSynch, currently available for both Windows and Mac OS X, is a presentation software application tailored towards evangelistic speakers with limited experience. The software has several essential features including the use of speaker notes during a presentation, support for independent slide and speaker note language, speaker note pagination with dynamic font scaling, editing of presentations and rich text speaker notes from within the application, and dynamic appeal video configuration. No known iOS application contains all of the PC software\u27s essential features. In this paper, we discuss the design and implementation of ShareSynch on the iOS platform. The iOS version of ShareSynch, developed in conjunction with ShareHim, mirrors functionality currently available in the PC software and also adds new features such as dynamically generated PDF documents, downloadable sermon series, and a new file format that provides for reduced storage consumption. ShareSynch was published in the iOS App Store on March 2, 2015

Integrating Smart Ceiling Fans and Communicating Thermostats to Provide Energy-Efficient Comfort
The project goal was to identify and test the integration of smart ceiling fans and communicating thermostats. These highly efficient ceiling fans use as much power as an LED light bulb and have onboard temperature and occupancy sensors for automatic operationbased on space conditions. The Center for the Environment (CBE) at UC Berkeley led the research team including TRC, Association for Energy Affordability (AEA), and Big Ass Fans (BAF). The research team conducted laboratory tests, installed99 ceiling fans and 12 thermostats in four affordable multifamily housing sites in California’s Central Valley, interviewed stakeholders to develop a case study, developed an online design tool and design guide, outlined codes and standards outreach, and published several papers.The project team raised indoor cooling temperature setpoints and used ceiling fans as the first stage of cooling; this sequencing of ceiling fans and air conditioningreducesenergy consumption, especially during peak periods, while providing thermal comfort.The field demonstration resulted in 39% measured compressor energy savings during the April–October cooling seasoncompared to baseline conditions, normalized for floor area. Weather-normalized energy use varied from a 36% increase to 71% savings, withmedian savings of 15%.This variability reflects the diversity in buildings, mechanical systems, prior operation settings, space types, andoccupants’ schedules,preferences, and motivations. All commercial spaces with regular occupancy schedules (and twoof the irregularly-occupied commercial spaces and one of the homes) showed energy savings on an absolute basis before normalizing for warmer intervention temperatures,and 10 of 13 sites showed energy savings on a weather-normalized basis. The ceiling fans provided cooling for one site for months during hot weather when the coolingequipment failed.Occupants reported high satisfaction with the ceiling fans and improved thermal comfort. This technology can apply to new and retrofit residential and commercial buildings

The creative symbiosis of composer and performer (An examination of collaborative practice in partially improvised works)
This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.This thesis comprises a portfolio of compositions with supporting commentary in addition to a general commentary on past and contemporary models of performance practice. The compositions all use elements of improvisation and are documented in recorded and score formats. Recordings and discussion of the rehearsal process of these works are also included. The thesis is divided into four parts. The first, entitled ‘Context’, examines issues of performance practice through reference to both historical and contemporary models. In this regard, particular attention is given to the work of Miles Davis and Peter Wiegold. Parts 2, 3 and 4 consist of the portfolio of original compositions with sub-headings as follows: ‘Beginnings’, ‘Transition’ and ‘Current Projects’. As a part of the commentary on the portfolio, the role of the performer as creative artist will also be examined
Natural Language Commanding via Program Synthesis
We present Semantic Interpreter, a natural language-friendly AI system for
productivity software such as Microsoft Office that leverages large language
models (LLMs) to execute user intent across application features. While LLMs
are excellent at understanding user intent expressed as natural language, they
are not sufficient for fulfilling application-specific user intent that
requires more than text-to-text transformations. We therefore introduce the
Office Domain Specific Language (ODSL), a concise, high-level language
specialized for performing actions in and interacting with entities in Office
applications. Semantic Interpreter leverages an Analysis-Retrieval prompt
construction method with LLMs for program synthesis, translating natural
language user utterances to ODSL programs that can be transpiled to application
APIs and then executed. We focus our discussion primarily on a research
exploration for Microsoft PowerPoint
Software for malicious macro detection
The objective of this work is to give a detailed study of the development process of a software tool for the detection of the Emotet virus in Microsoft Office files, Emotet is a virus that has been wreaking havoc mainly in the business environment, from its beginnings as a banking Trojan to nowadays. In fact, this polymorphic family has managed to generate evident, incalculable and global inconveniences in the business activity without discriminating by corporate typology, affecting any company regardless of its size or sector, even entering into government agencies, as well as the citizens themselves as a whole. The existence of two main obstacles for the detection of this virus, constitute an intrinsic reality to it, on the one hand, the obfuscation in its macros and on the other, its polymorphism, are essential pieces of the analysis, focusing our tool in facing precisely two obstacles, descending to the analysis of the macros features and the creation of a neuron network that uses machine learning to recognize the detection patterns and deliberate its malicious nature. With Emotet's in-depth nature analysis, our goal is to draw out a set of features from the malicious macros and build a machine learning model for their detection. After the feasibility study of this project, its design and implementation, the results that emerge endorse the intention to detect Emotet starting only from the static analysis and with the application of machine learning techniques. The detection ratios shown by the tests performed on the final model, present a accuracy of 84% and only 3% of false positives during this detection process.Grado en IngenierÃa Informátic

FederatedScope-LLM: A Comprehensive Package for Fine-tuning Large Language Models in Federated Learning
LLMs have demonstrated great capabilities in various NLP tasks. Different
entities can further improve the performance of those LLMs on their specific
downstream tasks by fine-tuning LLMs. When several entities have similar
interested tasks, but their data cannot be shared because of privacy concerns
regulations, federated learning (FL) is a mainstream solution to leverage the
data of different entities. However, fine-tuning LLMs in federated learning
settings still lacks adequate support from existing FL frameworks because it
has to deal with optimizing the consumption of significant communication and
computational resources, data preparation for different tasks, and distinct
information protection demands. This paper first discusses these challenges of
federated fine-tuning LLMs, and introduces our package FS-LLM as a main
contribution, which consists of the following components: (1) we build an
end-to-end benchmarking pipeline, automizing the processes of dataset
preprocessing, federated fine-tuning execution, and performance evaluation on
federated LLM fine-tuning; (2) we provide comprehensive federated
parameter-efficient fine-tuning algorithm implementations and versatile
programming interfaces for future extension in FL scenarios with low
communication and computation costs, even without accessing the full model; (3)
we adopt several accelerating and resource-efficient operators for fine-tuning
LLMs with limited resources and the flexible pluggable sub-routines for
interdisciplinary study. We conduct extensive experiments to validate the
effectiveness of FS-LLM and benchmark advanced LLMs with state-of-the-art
parameter-efficient fine-tuning algorithms in FL settings, which also yields
valuable insights into federated fine-tuning LLMs for the research community.
To facilitate further research and adoption, we release FS-LLM at
