Can mosfet specs influence half-bridge mofet driver ability?

S

seeker

So I'm having fun with IR2101 mosfet/IGBT half-bridge driver. I've checked typical schematic and tried implement "happy path" scenario. enter image description here I have created very same circuit as in application notes, and seems like bootstrap circuit does not work. I get following values:

Vcc = 12v, VB=11V, Vs = 11V when HIN=LIN=0 and same but Vb=11V and Vs=9v when HIN=LIN=1. Vgs = 11V in this case.

I've tried circuit simulator (yes, IR2101 even has PSPICE model) and result is even more funnier... enter image description here

Can anyone suggest what can go wrong here? Capacitor is 1uF which should be more than enough for gate charge of 30nC. I also thought maybe diode is not fast enough, but it's schotky diode with very fast recovery.

What the garlic is that pt.2? (Plant identification help needed)

I have sown some garlic cloves in a pot (I only have a balcony, don't judge). And... something came out of the pot, but it's not garlic, and I'm very curious what it might be: Mystery plant Mystery plant, image two

I even mistook it for garlic initially, but it's completely inedible, and in fact, can barely be chewed through in any manner - the leaves are pretty tough. As far as I could tell by rummaging in the ground, there are no cloves to this beastie, and the roots seem to go quite far down. Google Lens identifies that as Chives, but I can guarantee you it's not (I actually do have chives, in a pot beside this one). In this case, you can see some actual garlic that caught on, chilling in the background, wondering what kind of neighbor is that. It definitely feels like a weed, but I still wanted to find out what it could be before it goes out.

Any educated guesses?

What would happen if you use warm base on a compressor ice cream machine?

Note: This question is for an ice cream machine WITH a compressor

Pretty much all recipes for ice cream/gelato call for completely chilling the mixture before starting to churn.

I get that for "passively" cooled machines (compressorless) it's important, so that you don't loose any of the pre-cooling you've done to the hardware.

Does it actually matter for a compressor-based machine? The machine can certainly cool it down without a hitch, but would it impact the final texture?

Attempting to simplify Fiege-Fiat-Shamir Identification

My understanding of the Fiege-Fiat-Shamir protocol, sourced from "RSA and Public-Key Cryptography" by Richard A. Mollin is as below:

  1. A third party chooses two large primes $p$ and $q$, sharing $n = pq$.
  2. Alice has a secret value $s_a$ and shares a number $t_a = s_a^2 \mod n$.
  3. Alice picks a random $m \in \mathbb{N}$ and sends $w = m^2 \mod n$ to Bob.
  4. Bob picks a challenge $c \in \{0, 1\}$ and sends that to Alice.
  5. Alice computes $r = ms_a^c \mod m$ and sends that to Bob.
  6. Bob computes $r^2 = m^2s_a^{2c}$, and he can compare that to the publicly known $wt_a^2$, which should be identical if Alice does indeed know $s_a$. The security of this protocol is based on the fact that it is difficult to solve quadratic modular congruences with unfactored moduli.

My text elaborates that there is a method that an attacker can use to impersonate Alice with a 50% success rate, so this is done $a$ times and the probability that this works becomes $2^{-a}$.


If my understanding of this is correct, then one could use a similar protocol, but without the 50% chance of failure:

  1. As before, a third party selects $p$ and $q$, sharing $n = pq$.
  2. Alice picks a random $m$ and sends $w = m^2 \mod n$ to Bob.
  3. Alice sends $r = ms_a \mod n$ to Bob.
  4. Bob computes $r^2 \mod n$ and confirms that it's equal to $mt_a$.

Again, because neither $w$ nor $t_a$ are easy to compute, this seems secure.

I assume that this doesn't work. Why not? Why does Fiege-Fiat-Shamir require that Bob send a challenge?

Zencash uses your passphrase to identify AND unlock a wallet - how is this secure?

When looking into Zencash I stumbled into myzenwallet.io (by the Zencash creators), which gives you the option to enter a passphrase to generate a wallet (seems normal), but then after creating your wallet you can come back later and open your wallet by simply re-entering your passphrase again... this was unexpected and had me not only wondering about how it worked, but also wondering whether whatever means were used to achieve this would remain secure in the future.

Given that I don't need to identify the resource I'm unlocking, but rather just hand over the passphrase, I'm left to assume that their system generates a token by hashing my passphrase a number of times to generate my "master address" or "account ID" (I just made those terms up, because Zencash gives you many addresses, so I also assume you have some sort of master address / account ID), and then also using that same passphrase to lock / authenticate (not to encrypt though, right?) the wallet.

Chromatic number of distance graphs on the integers with restricted prime divisors

Let $P$ be a finite set of prime numbers. Define the distance graph $G(P, n)$ on the vertex set $V = \{1, 2, ..., n\}$ where two vertices $a$ and $b$ are connected by an edge if and only if $|a-b|$ is a product of primes in $P$. Denote the chromatic number of $G(P, n)$ by $\chi(G(P, n))$.

Can we find a function $f(k)$ such that $$ \chi(G(P, n)) \leq f(k) $$ for all $n$ and all sets $P$ with $|P| = k$?

Minimal bipartite graph density in the log-edge-density version

A graphon is a bounded measurable symmetric function $W:[0,1]^2\to [0,1]$. Let $\mathcal{W}$ denote the set of all graphons. For any $p\in [0,1]$, let $\mathcal{W}_p$ denote the set of all graphons $W$ such that $\int W=p$. For any graphon $W$ and any bipartite graph $H$ with bipartition $(A,B)$ where $|A|=v_1,\ |B|=v_2$, the density of $H$ in $W$ is defined as: $$t(H,W)=\int_{[0,1]^{v(H)}}\prod_{ij\in E(H)}W(x_i,y_j)\prod_{i\in A} dx_i \prod_{i\in B} dy_j .$$ Define $h(H,W)=\log_{\int W}t(H,W).$ For any $p\in (0,1)$ does the following hold? $$\max_{W\in\mathcal{W}}h(H,W)=\max_{W\in\mathcal{W}_p}h(H,W).$$
