1. CAPACITATED LOT SIZING AND SCHEDULING WITH ORDER ACCEPTANCE AND DELIVERY TIME WINDOWS: MATHEMATICAL MODEL AND A MIP-BASED HEURISTIC
ABSTRACT This research addresses a lot sizing and scheduling problem inspired by a real-world production environment where the customers make advanced orders and the industry need to decide which orders will be accepted with the aim of maximizing the profit respecting the production capacity constraints. Orders are composed of different types of items which

2. Comparison between the application of the conventional mine planning and of the direct block scheduling on an open pit mine Project
Abstract Historically, since the 60's, traditional mine planning consists of several distinct stages: 1) Definition of the ultimate pit - the portion of the blocks that results in the greatest total value; 2) Pushback selection - based on the generation of nested pits, obtained with the change in the value of the ore price; 3) Long-term production scheduling

3. A NEW MATHEMATICAL MODEL FOR THE WORKOVER RIG SCHEDULING PROBLEM
ABSTRACT One of the most important activities in the oil and gas industry is the intervention in wellsfor maintenance services, which is necessary to ensure the constant production of oil. These interventions are carried out by workover rigs. Thus, the Workover Rig Scheduling Problem (WRSP) consists of finding the best schedule to service the wells while con

4. A non-invasive plant-based probe for continuous monitoring of water stress in real time: a new tool for irrigation scheduling and deeper insight into drought and salinity stress physiology
The non-invasive, magnetic leaf patch clamp pressure probe (also termed ZIM-probe) allows for the first time to measure continuously turgor pressure changes of plant leaves over long periods of time with high precision and in real time. The probe has become an important tool in plant physiology, molecular biology and ecology, but also in agriculture because

5. Automação de um sistema de pulverização para aplicação de agroquímicos a taxa variada usando injeção direta / Automation of a direct injection sprayer system for variable rate application of agrochemicals
In this work, the automation of a direct injection sprayer system for variable rate application of agrochemicals is presented. The automation of the sprayer system assembled on a laboratory static bench is based on a programmable controller with real time capabilities. Variable rate sprayer with direct injection systems allow multiple agrochemical applicatio

7. Proposta de um modelo em programação linear para a solução de problemas de sistemas produtivos job shop com setup dependentes da sequência / Proposal of a linear programming model for solving problem systems job shop production with setup times sequence-dependent
Sequencing problems are very common, they happen every time there is a choice regarding the order in which several tasks can be performed. The business can be an airline, a hotel, a computer manufacturer or a university; these issues are part of their routine. The application of the sequencing techniques allows, for example, reducing the costs and fastening

8. Modelo de decisão para a programação de entrega de concreto produzido em centrais. / A decision model for the problem of scheduling concrete delivery produced in concrete batch plants.
This paper addresses the problem of scheduling concrete delivery produced in concrete batch plants. Such scheduling comprises the decisions of which center should serve each customer and what time each delivery vehicle should be loaded, so as to maximize the total marginal revenue of the system. Vehicle loading capacity constraints per center, fleet availabi

9. MONITORING FLEXIBLE RISERS WITH OPTICAL FIBER SENSORS / MONITORAMENTO DE RISERS FLEXÍVEIS COM SENSORES A FIBRA ÓPTICA
The interest in structural health monitoring of flexible risers has grown significantly in recent years. For ducts that are already reaching their design life, monitoring systems can provide early warnings of potential failures and also assist the operator in scheduling downtime. Different techniques are being tested by operators of flexible pipes such as au

10. "Why caipirinha?"- the online via chat laddering technique CAN answer
As customers are becoming increasingly connected to the internet, this means that they are available for online interviews, thus opening up a space for investigating research methods, especially qualitative research, in an attempt to identify how to adapt data collecting instruments to the so-called "connected customer era". In this context, the focus of thi

11. Constraint-driven test scheduling for NoC-based systems
On-chip integrated network, the so-called networkon- chip (NoC), is becoming a promising communication paradigm for the next-generation embedded core-based system chips. The reuse of the on-chip network as test access mechanism has been recently proposed to handle the growing complexity of testing NoC-based systems. However, the NoC reuse is limited by the o

12. Proposta de melhoria de tempo de resposta para o protocolo FTT-CAN : estudo de caso em aplicação automotiva
Embedded computing systems have become widely used in many areas. The greater part of those systems has time constraints and therefore they can be characterized as real time embedded systems. Nowadays, distributed computing has reached the embedded application, where some fieldbuses are already being used as communication platforms. Some important researches
