Automatic Grasping System and Hybrid Controller Towards Multi-Drone Parcel Deli...

This paper presents the development of an autonomous grasping mechanism for drone-based parcel delivery systems towards developing capabilities for in-flight package transfer. The approach integrates a mechanical gripper fitted with sensors and a pose estimation method for parcels, all coordinated through a hybrid Model Predictive Control (MPC) architecture. The gripper’s mechanical structure and prototype are ...

The Asymmetrical Face of a Potential Systemic Disease: A Pattern to Recognize

Parry-Romberg syndrome (PRS) is a rare disorder characterized by a progressive atrophy of the skin, subcutaneous tissue, muscle, and bone of the hemiface, being more common in females. The etiology is unknown, and symptomatology is variable, beginning in the first two decades of life and evolving over 20 years or more. There is no specific treatment, and prognosis depends on the severity of lesions. We report t...

Peritoneal Carcinomatosis: when everything is not what it seems

Malignant peritoneal mesothelioma (MPM) is a rare neoplasm with a low incidence rate worldwide but high morbidity and mortality rates. Due to its rarity, the studies are scarce. We present a case of a 73-year-old woman admitted to the internal medicine unit with constitutional syndrome, abdominal pain, and ascites. Throughout the investigation, aspects suggestive of peritoneal carcinomatosis were identified. An...

Undercover peripheral arterial disease

Peripheral arterial disease is a frequently underdiagnosed disease that can severely affect the quality of life. We present a clinical case of a 62-year-old smoker post-menopause woman with a mild stroke. Further investigation revealed a severe disseminated arterial disease. Due to multidisciplinary and timely interventions, peripheral ischemia was prevented successfully. In fact, this patient had polyvascular ...

Avaliação direta e indireta dos níveis de atividade física dos alunos de fisiot...

Introdução e Objetivos: A promoção da atividade física (AF) é um dos principais objetivos da Organização Mundial de Saúde (OMS) e da World Physiotherapy (World Physio) no âmbito da prevenção de doenças não transmissíveis e a implementação de hábitos de vida saudáveis. Em Portugal reforçou-se este objetivo com o Programa Nacional de Atividade Física (PNAF), destacando que os profissionais de saúde terem um papel...

Trajectory planning and control for drone replacement for multidrone cinematogr...

This work addresses the problem of trajectory planning and control for a team of drones, so that a vehicle that is following a target as part of a multi-vehicle formation flight can be safely replaced with minimum impact on the formation objectives. An optimal trajectory generation method is presented, which relies on formulating a nonlinear optimization problem with constraints imposed by the physical limitati...
