Quais os sistemas de controle de constitucionalidade? Explique a origem de cada um deles.Os sistemas de controle de constitucionalidade são o difuso e o concentrado. O controle difuso tem origem no direito norte-americano, a partir do caso Marbury v. Madison, e permite que qualquer juiz ou tribunal declare a inconstitucionalidade de uma norma no caso concreto. Já o controle concentrado tem origem no modelo europeu, idealizado por Hans Kelsen, no qual a análise da constitucionalidade é atribuída
Q1. Explain IoT in Detail + Vision + Sources + Technology Behind IoT
**Definition:** IoT refers to a network of physical devices embedded with sensors, software, and connectivity to collect and exchange data over the internet without human intervention.
**Vision of IoT:**
- Every physical object connected to the internet
- Smarter environments (homes, cities, industries)
- Data-driven decisions in real time
- Reduced human effort through automation
**Sources of IoT:** Sensors, RFID tags, smartphones,
Ethnoarchaeology = study of living traditional societies to understand past built forms and human behavior
Helps interpret relationship between climate, materials, culture, and architecture
Example: Kutch Bhunga houses, Gujarat
Circular plan (3–6 m diameter)
Thick mud walls (300–450 mm)
Conical thatch roof on wooden frame
Small windows and low doors
Cluster-based settlement planning
Observed to perform well in 2001 Bhuj earthquake
Interpretation:
Circular form → better
SOLID/modularity:
- lecturer skeptical of SOLID as design recipe
- real goal = modularity
SRP:
- “single responsibility” / “one reason to change”
- vague, changing definitions
- hard to apply consistently
- better to think in terms of concepts/roles
OCP:
- open for extension, closed for modification
- change behaviour without editing original class
- often achieved with polymorphism/template method
LSP:
- subtype must be valid substitute for parent/interface
- not just same method signatures
- check...
Q-2 (A) Ignition Delay (SI vs CI Engines)
In SI engines, ignition delay (ignition lag) is the time interval between the spark and the start of combustion (AB phase). It depends on factors like temperature, pressure, air-fuel ratio and fuel structure.
In CI engines, ignition delay is the time interval between the start of fuel injection and the start of combustion (AC phase). During this period, fuel undergoes atomization, vaporization and mixing with air. It consists of physical delay and chemical

Rectangular beam: b = 100 mm, d = 250 mm, L = 3 m, w = 40 kN/m
→ Find τmax + distribution
16.2
Triangular section: b = 100 mm, h = 150 mm, F = 13.5 kN
→ Find τmax + distribution
16.3
Circular section: d = 100 mm, F = 30 kN
→ Find τmax + distribution

Hey [Name]! I heard about [the situation], and I completely get where you're coming from -that's a huge decision" / "that sounds really stressful" / "I know how overwhelming that can feel"]. Let me share a few ideas that could really help you hit the ground running.First, I'd strongly recommend [_action_]. This is particularly important because [reason]. It'll give you a real sense of [peace of mind / direction / long-term security / confidence].Next, think about -[different angle — finances /
...OMG’s Model-Driven Architecture (MDA) The Object Management Group (OMG) has defined its own comprehensive proposal for applying Model-Driven Engineering (MDE) practices to system’s development: MDA (Model-Driven Architecture) • Four Principles of MDA • Models must be expressed in a well-defined notation to enable effective communication and understanding • Systems specifications must be organized around a set of models and associated transformations (mappings and relations between multi-
(1) Computer Security: The protection afforded to an automated information system in order to attain the applicable objectives of preserving the Integrity, Availability, and Confidentiality of information system resources, including hardware, software, firmware, information, data, and communication. (10) Buffer overflow/overrun: When a process tries to store data beyond the limits of a fixed-size buffer, overwriting adjacent memory locations. Buffer can be located in stack, heap, or data section...
