Quiz 1 : * What is the fundamental difference between a homogeneous mixture and a heterogeneous mixture? - A homogeneous mixture has a uniform composition throughout, while a heterogeneous mixture has regions with different compositions. * What is the primary distinguishing factor between an element and a compound? - An element consists of only one type of atom, while a compound is made up of two or more types of atoms chemically bonded together.* What is the relationship between milliliters and
...E -> E1 + T E.val = E1.val + T.val }
E -> T { E.val = T.val }
T -> T1 * F { T.val = T1.val * F.val }
T -> F { T.val = F.val }
F -> num { F.val = num.value }
(ii) Evaluation using SDTS (bottom-up):
F -> num(4): F.val = 4
F -> num(2): F.val = 2
F -> num(3): F.val = 3
T -> F (for num(2)): T.val = F.val = 2
T -> T * F: T.val = T.val (from num(2)) * F.val (from num(4)) = 2 * 4 = 8...
• The term “ money market ” is a misnomer. Money (currency) is not actually traded in the money markets. • The securities in the money market are short term with
high liquidity; therefore, they are close to being money.
Money Markets Defined 1. Usually sold in large denominations ($1,000,000 or
more) 2. Low default risk3. Mature in one year or less from their issue date, although most mature in less than 120 days
• The banking industry should handle the needs for short - term. • Banks...
A semaphore is a signaling mechanism used to manage access to shared resources in multitasking systems like RTOS. It ensures that only one task or a limited number of tasks can access a critical resource at a time, preventing issues like race conditions, data corruption, deadlocks, and inconsistent behavior.
When multiple tasks try to access a common resource, semaphores help synchronize their operations by:
Making a task wait if the resource is busy.
Allowing access when the resource becomes free.
Problem: What are you trying to solve? Clearly define your research question.
Plan: How will you collect data? Choose a sampling method & variables.
Data: Collect and clean data (e.g., remove errors, handle missing values).
Analysis: Use EDA (plots & stats) and model the relationships (e.g., regression).
Conclusion: Answer your research question. Be careful about generalizing!
| Method | Description | Pros | Cons |

Purpose: Help people handle mental health challenges through therapy or medical treatment.
Two Main Types:
Psychotherapies (Talk Therapy): Focus on thinking, emotions, coping skills.
Biomedical Therapies: Focus on changing brain chemistry/structure.
Work with trained therapist.
Help understand problems, emotions, relationships.
Useful for stress, anxiety, depression, trauma.

M/EEG Hardware: 1. Basics: EEG: Measures electrical potential (Volts) via scalp electrodes. MEG: Measures magnetic flux (Teslas) using sensors close to the scalp. Invasive methods: Electrocorticography (ECoG), depth recordings. MEG "sees less but sees better" - David Cohen 2. EEG Details: Signal strength: Scalp EEG: 10–100 µV (peak-to-peak). Dura (brain surface) EEG: 10–20 mV; Electrodes: Silver (Ag) + Silver chloride (AgCl), Rely on electrochemical reactions (oxidation/reduction). Placement:...

Content Vocabulary
Girder – The girder supports the floor joists by carrying the weight of the structure above it.
Box sill – A box sill is constructed by placing the sill plate on the foundation and attaching the band joist.
Subflooring – The subflooring is secured to the joists to provide a stable base for the finished flooring.
Crown – The crown of a joist should always be positioned upward to account for deflection over time.
Bridging – Bridging between floor joists prevents...
(1) Centrifugal force – Outward force in rotating reference frame. Coriolis Force – Deflection due to Earth’s rotation. Centripetal force – Inward force keeping circular motion. Geostrophic flow – Balance: Coriolis and pressure gradient. Inertial flow – Only Coriolis force acts. Cyclostrophic flow – Pressure balances centrifugal, no Coriolis. Gradient flow – Curved flow with all forces.
(2) Yes – Longer moment arm (larger R) → larger centrifugal acceleration. Yes – Higher
