A service is any activity, process, or performance offered by one party to another, which is intangible in nature and does not result in ownership of anything. Services are designed to meet customer
Core system problems persist: Variability, congestion, coordination, flow.
Production system layouts: Layouts depend on volume, variety, and material flow. And determine how work flows through the system between work centers.
Product line Layout:(flow lines)FAST, PREDICTABLE, INFLEXIBLE. Resources arranged in processing order, follows single fixed path, designed for mass production. e.g. automotive assembly & consumer electrics. Pros: large outputs, efficiency. CONS: long switchovers/
f) Define (i) Diffusion current (ii) Drift current & (iii) Barrier potential in a pn junction.
Ans:
1. Diffusion Current: Due to the concentration gradient,
majority carriers move across the junction (holes from p-side to n-side and electrons from n-side to p-side). This motion constitutes the diffusion current.
2. Drift Current: The electric field in the depletion region
causes minority carriers to move across the junction (holes from n-side to p-side and electrons from p-side to n-side). This
Interaction Design (IxD): Designing interactive products to support the way people communicate and interact in their everyday and working lives. Winograd → “Designing spaces for human communication and interaction. Thackara → Focuses on the why and how of daily interactions. Saffer → “Art of facilitating interactions between humans through products and services.” Key idea: It’s about creating good user experiences, not just working systems. -------- Goal of interaction design: Reduce...

CHAPTER 1: ACCOUNTING INFORMATION SYSTEMS (AIS)
What Is a System?
A system is two or more interacting parts (subsystems) working together to achieve one or more goals.
Example:
A company is a system.
• Sales department
• Accounting department
• HR department
All work together to earn profit.
Goal Conflict
Occurs when one subsystem’s goal hurts the overall organization.
Example:
Sales offers heavy discounts to increase sales numbers, but profits fall.
Goal Congruence
Occurs when subsystem goals...
Enunciat: Una màquina de vapor que extreu Qh=700 MJ de la font calenta (Th=600 ºC), fa un treball net W=300 MJ. La font freda està a Tc=120 ºC. Determineu:
a) Rendiment de Carnot (Teoric): E_c = 1 - (Tc_K / Th_K) = 1 - (393 / 873) = 0,5498 = 54,98%
b) Treball màxim: W_max = Qh * E_c = 700 * 0,5498 = 384,86 MJ
c) Rendiment real: E_r = W / Qh = 300 / 700 = 0,4285 = 42,85%
d) Treball perdut: W_i = W_max - W = 384,86 - 300 = 84,86 MJ

P.1. Explicar breument les idees principals del text i com hi apareixen relacionades. El text estableix el criteri fonamental de l'empirisme: totes les nostres idees deriven obligatòriament d'impressions prèvies. L'autor diferencia les impressions, que són clares, fortes i evidents, de les idees, que són còpies febles i confuses. Aquest principi s'utilitza com a eina analítica per descartar conceptes metafísics: si un terme no es pot remetre...
